This area includes tracts 427, 428, 471, 472, 515, and 516, that will be offered for sale in March 1982 as part of Lease Sale 67.
The sea floor of this region is, slightly hummocky and is underlain by salt diapirs that are mantled by early Tertiary shale. Most of the shale is overlain by younger Tertiary and Quaternary deposits, although locally some of the shale protrudes the sea floor. Because of proximity to older Mississippi River sources, the sediments are thick. The sediment cover shows an abundance of geologic phenomena such as horsts, grabens, growth faults, normal faults, and consolidation faults, zones with distinct and indistinct parallel reflections, semi-transparent zones, distorted zones, and angular unconformities.
The major feature of this region is a N-S linear zone of uplifted and intruded sedimentary deposits formed due to diapiric intrusion.
Small scale graben development over the crest of the structure can be attributed to extension and collapse. Large scale undulations of reflections well off the flanks of the uplifted structure suggest sediment creep and slumping. Dipping of parallel reflections show block faulting and tilting.
Air gun (5 and 40 cubic inch) records reveal at least five major sequences that show masked onlap and slumping in their lower parts grading into more distinct parallel reflections in their upper parts. Such sequences can be related to local uplift and sea level changes. Minisparker records of this area show similar sequences but on a smaller scale. The distinct parallel reflections often onlap the diapir flanks. The highly reflective parts of these sequences may represent turbidite-type deposition, possibly at times of lower sea level. The acoustically more transparent parts of each sequence may represent deposits containing primarily hemipelagic and pelagic sediment.
A complex ridge system is present along the west side of the area and distinct parallel reflections onlap onto this structure primarily from the east. Much of this deposition may be ascribed to sedimentation within a submarine canyon whose position is controlled by this ridge.

The cochair for this study group (the Secretary of the Interior's Field Representative, Denver, Colorado, and the Natural Resources Coordinator for North Dakota) further articulated the charge concerning the second of these two questions to include three steps: 1) development of a general plan for preservation and protection of migratory waterfowl and their associated wetland habitat; 2) a comprehensive analysis of alternative strategies, including opportunities and constraints, for achieving the goals articulated in Step 1; and 3) design of a coordinated state-federal public information program to assist in plan implementation.
\nIn order to obtain input from a variety of interests, the joint study group initiated step 2 activities with a five-day workshop in Bismarck, N. D.; December 8-12, 1980. The objectives of the workshop were: 1) to identify alternative strategies for preserving and enhancing waterfowl production habitat in North Dakota; 2) to identify opportunities and constraints associated with those alternatives; and 3) to promote communication and understanding of the implications of those alternatives for all affected parties. To achieve these objectives, the workshop utilized a group of concepts and techniques collectively known as Adaptive Environmental Assessment (AEA).
\nDeveloped by Dr. C. S. Holling and his co-workers at the University of British Columbia, the AEA process involves planners, managers, scientists, and other interested parties in a structures atmosphere whose focus is the construction and examination of a computerized simulation model of the resource system under consideration. The modeling process is used to promote communication, identify pertinent issues, identify key data gaps and uncertainties, direct research efforts to fill those gaps, and explore the possible consequences of various management alternatives.
\nThe workshop, which was facilitated by the AEA Group of the U.S. Fish and Wildlife Service (FWS), was attended by approximately 25 invited participants representing a variety of interests concerned with the wetlands protection issue in North Dakota. During the week workshop participants conceptualized and constructed a computerized simulation model incorporating many of the hydrologic, agricultural, and wildlife aspects of the wetlands issue. During the process of constructing this model and examining its behavior, participants identified several interesting alternative strategies that may prove useful in an overall wetland protection program, along with a variety of constraints associated with each.
\nPerhaps the most interesting of these alternatives revolve around the idea that there may be a variety of cases in which water can be retained on the land, with concommitant benefits both for wildlife and flood control, without detriment to agricultural productivity. Examples of this kind of activity include flooding of previously drained Type I wetlands in summer fallow areas, installation of smaller drains in Type I and III wetlands to reduce the rate at which water runs off in the spring, and use of strategically located gates in drainage channels associated with the state highway system to slow runoff and create wetland habitat.
\nSeveral other alternatives discussed at the workshop are related to the notion of using available, uncommitted water supplied to enhance or create wetlands. Several cases were cited in which more certain water supplies would be useful in increasing waterfowl production or reducing disease problems, especially in dry years. Water for such purposes might come from a variety of current of proposed water development projects, both large and small scale.
\nFinally, the potential for re-establishment of \"unsuccessfully\" drained (i.e., not consistently usable for agricultural purposes) wetlands was discussed at some length. There are apparently substantial acreages of such wetlands in North Dakota and a program to acquire and rehabilitate them might be of considerable utility.
\nThe workshop was thus successful in accomplishing its first two objectives--identification of alternative strategies, opportunities, and constraints. However, it would be naive to suppose that any of the alternatives discussed offers a complete, simple solution to the wetlands issue in North Dakota. The most important result of the workshop may therefore be that which was accomplished relative to the third objective--promotion of communication and understanding. It was gratifying and encouraging to see the spirit of communication and cooperation that developed by the end of the workshop. The fact that representatives of many of the interests concerned with the wetlands issue participated in an open exchange of ideas and information marks an important step forward. We believe that it is imperative that this cooperative attitude be maintained, and that there are a variety of ways in which this might be accomplished. Perhaps the simplest would be a small-scale pilot project and research effort to determine the effects of wetland maintenance on summer fallow areas. Such a research program would provide not only useful information, but an opportunity for many of the affected interests to begin working toward mutually acceptable solutions to the overall wetlands issue.

Province of Saudi Arabia. The quadrangle is located between lat 20°00'N. and 20°30'N. and long 43°00'E. and 43°30'E. It is underlain by volcanic, volcaniclastic, and plutonic rocks of late Precambrian age. Most of the quadrangle consists of a large, asymmetric gneiss dome that extends far to the north and south of the quadrangle. Parallel with the eastern border of the quadrangle, part of the extensive, serpentinite-bearing, Nabitah fault zone probably represents a major suture between crust of Jiddah age to the west and younger crust of Halaban age to the east.
An excellent section of the Halaban-age crust is exposed in and adjacent to the gneiss dome. At the eroded top of the section to the east, calc-alkalic volcanic rocks of the Halaban group are dominantly andesite but range from basalt to dacite. Beneath the volcanic rocks, comagmatic, subvolcanic plutonic rocks include predominantly diorites but range from gabbro to trondhjemite. These rocks were formed during island-arc volcanism and plutonism from about 780 m.y. to 720(?) m.y. ago. About 725 m.y. ago this primitive crust was thickened by emplacement of large intermediate-crustal depth plutons of hornblende tonalite and hornblende granodiorite. Compressional tectonism produced folds and faults with northern trends and accompanying greenschist metamorphism.
Granitic plutonism began 625 m.y. ago, perhaps in response to a major continental collision between the Halaban crust and a continental mass to the east. Granodiorite-monzogranite comprising the Wadi Musayrah batholith formed the core of the Jabal al Qarah gneiss dome as the dome rose. The low-density, intermediate-depth, plutonic rocks of the Halaban crust were converted to orthogneisses as they rose. Strong compression resulted in a large west-directed thrust, the Nabitah fault zone, containing serpentinite. Subsequently, plutons of monzogranite, syenogranite, and alkali-feldspar granite intruded the eroding crust at progressively shallower levels until about 600 m.y. ago. After this time the polymictic conglomerate of the Murdama group was deposited over the youngest granite--the alkali-feldspar granite at Jabal ash Shawhatah al Hamrah; the conglomerate was subsequently deformed.
Continued compression of the now relatively thick continental crust resulted in the Najd faulting event about 570 m.y. ago. Two northwest-trending faults in the quadrangle have left-lateral displacement; one has 7 km of offset. These two faults are small but are characteristic of the large Najd fault zones farther north. Throughout the quadrangle, northwest-trending Najd fracturing was pervasive and many of these secondary fractures were filled with diabase dikes of Najd age. The diabase dikes and the deeper, non-exposed mafic plutons induced small-scale, but widespread hydrothermal convection and alteration that produced small quartz veins locally mineralized with gold. Quartz-vein gold was mined on a small scale by ancient miners in several areas. An extensive gold placer was worked about 2,600 years ago in a 50 km2 area at Jabal Mokhyat. None of these deposits are economical by present-day standards.
