The basal Onverwacht sediments lie approximately 10,000 meters stratigraphically below the Fig Tree sedimentary rocks, from which similar organic microstructures have been interpreted as alga-like microfossils. The Onverwacht spheroids and filaments are best preserved in black, carbon-rich cherts and siliceous argillites interlayered with thick sequences of lavas.

Comparisons are made of the minor-element abundances between districts and within the paragenetic sequence in individual districts.The ore of the Illinois-Kentucky fluorite district is characterized by greater abundance of minor elements than in other Mississippi Valley deposits, by large fractionation of silver between galena and sphalerite, and by a low ratio of antimony to silver in galena. Silver and antimony are concentrated in the galena and show a marked zonal pattern within the district. Sphalerite is high in cadmium, gallium, and germanium.The Upper Mississippi Valley zinc-lead district differs markedly from the Illinois-Kentucky fluorite district in minor-element concentrations and distribution. The minor elements are much less abundant, and silver is slightly more concentrated in sphalerite than in galena.Several analyses of minor elements in ore minerals from the Southeast Missouri lead district are given for comparison.It is concluded that the minor elements were largely leached from the basement by convective circulation of heated oilfield brine.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.63.6.655","usgsCitation":"Hall, W.E., and Heyl, A., 1968, Distribution of minor elements in ore and host rock, Illinois-Kentucky fluorite district and Upper Mississippi Valley zinc-lead district: Economic Geology, v. 63, no. 6, p. 655-670, https://doi.org/10.2113/gsecongeo.63.6.655.","productDescription":"16 p.","startPage":"655","endPage":"670","costCenters":[],"links":[{"id":373143,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Kentucky","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.296875,\n              36.923547681089296\n            ],\n            [\n              -86.60522460937499,\n              36.923547681089296\n            ],\n            [\n              -86.60522460937499,\n              38.565347844885466\n            ],\n            [\n              -89.296875,\n              38.565347844885466\n            ],\n            [\n              -89.296875,\n              36.923547681089296\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"63","issue":"6","noUsgsAuthors":false,"publicationDate":"1968-09-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Hall, Wayne E.","contributorId":89955,"corporation":false,"usgs":true,"family":"Hall","given":"Wayne","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":784565,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heyl, Allen V.","contributorId":17678,"corporation":false,"usgs":true,"family":"Heyl","given":"Allen V.","affiliations":[],"preferred":false,"id":784566,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The flow patterns indicate numerous zones of ground-water recharge and discharge controlled by topography, varying thicknesses of geologic units, variation in permeabilities, and the configuration of the basement rock surface. Variations in streamflow along a reach of the Yellow Medicine River agree with the subsurface flow system. Increases and decreases in runoff per square mile correspond, apparently, to ground-water discharge and recharge zones. Ground-water quality variations between calcium sulfate waters typical of the Quaternary drift and sodium chloride waters typical of the Cretaceous rocks are caused by mixing of the two water types.

Complete cell parameters, 2V measurements, and bulk composition are given for 11 feldspar samples. The 131 and 131 reflections for these and 58 additional samples show the following structural types in the potassic phase: orthoclase only; orthoclase with subordinate maximum or near-maximum microcline (obliquity = 0.75–1.00); orthoclase with subordinate intermediate microcline (obliquity = 0.64–0.71); and intermediate microcline (obliquity = 0.56–0.77) with subordinate orthoclase. Within the pluton different feldspar structural types occur in zones whose boundaries are approximately parallel to contacts with younger intrusive rocks cutting the Rader Creek pluton but are, in places, nearly perpendicular to zonation within the pluton defined by rock composition. In general, the orthoclase zone is closest to the contact with younger intrusives; the intermediate microcline zone is the most distant. Bulk compositions of alkali feldspar are more potassic in the orthoclase zone than elsewhere. The data suggest a complex history for the alkali feldspar, involving at least two stages: 1. Exsolution and partial inversion of orthoclase to intermediate microcline during cooling of the Rader Creek pluton; 2. Transformation of the intermediate-microcline assemblage to orthoclase during reheating of the pluton at the time of intrusion of younger plutons of the batholith. The transitional stage in this transformation is characterized by orthoclase co-existing with subordinate microcline, whose obliquity usually approaches that of maximum microcline.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/petrology/9.3.331","usgsCitation":"Tilling, R.I., 1968, Article navigation zonal distribution of variations in structural state of alkali feldspar within the Rader Creek pluton, Boulder Batholith, Montana: Journal of Petrology, v. 9, no. 3, p. 331-357, https://doi.org/10.1093/petrology/9.3.331.","productDescription":"28 p.","startPage":"331","endPage":"357","costCenters":[{"id":153,"text":"California Volcano Observatory","active":false,"usgs":true}],"links":[{"id":376224,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Boulder Batholith, Montana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.7581787109375,\n              45.57175504130605\n            ],\n            [\n              -111.68701171875,\n              45.57175504130605\n            ],\n            [\n              -111.68701171875,\n              46.65697731621612\n            ],\n            [\n              -112.7581787109375,\n              46.65697731621612\n            ],\n            [\n              -112.7581787109375,\n              45.57175504130605\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"9","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Tilling, Robert I. 0000-0003-4263-7221 rtilling@usgs.gov","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":2567,"corporation":false,"usgs":true,"family":"Tilling","given":"Robert","email":"rtilling@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":792403,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

As the crust cools and increases&nbsp;</span>in<span>&nbsp;thickness following stagnation of the&nbsp;</span>lake<span>, existing cracks extend downward and new cracks open.

Cracks initiate at temperatures ranging from ambient to about 900°C, and propagate downward into parts of the crust near 1000°C.
