Rock pushing and sampling under rocks on Mars
H. J. Moore, S. Liebes Jr., D.S. Crouch, L.V. Clark
1978, Professional Paper 1081
Viking Lander 2 acquired samples on Mars from beneath two rocks, where living organisms and organic molecules would be protected from ultraviolet radiation. Selection of rocks to be moved was based on scientific and engineering considerations, including rock size, rock shape, burial depth, and location in a sample field. Rock...
Contact-metasomatic magnetite deposit, Medfra Quadrangle, Alaska
M.L. Throckmorton, William Wallace Patton
1978, Open-File Report 78-26
A small contact-metasomatic magnetite deposit was discovered in the Medfra quadrangle, Alaska, in 1976. It occurs at the contact between a Cretaceous or early Tertiary quartz monzonite stock and Paleozoic limestone and dolomite. The ore is a magnetite-clinohumite-hematite rock that contains up to 60 volume percent magnetite and 76 weight...
The structure and stratigraphy of the Pen Argyl Member of the Martinsburg Formation in Lehigh and Berks counties, Pennsylvania
Gary George Lash
1978, Open-File Report 78-391
The Pen Argyl Member, the upper claystone slate member of the Martinsburg Formation, was studied in three quadrangles in Lehigh and Berks Counties, Pennsylvania. Graptolites collected from the Pen Argyl Member at Lehigh Gap indicate a lower Upper Ordovician (Edenian-Maysvillian) age for the Pen Argyl Member. The Pen Argyl Member...
FORTRAN programs for calculating nonlinear seismic ground response in two dimensions
W. B. Joyner
1978, Open-File Report 78-287
The programs described here were designed for calculating the nonlinear seismic response of a two-dimensional configuration of soil underlain by a semi-infinite elastic medium representing bedrock. There are two programs. One is for plane strain motions, that is, motions in the plane perpendicular to the long axis of the structure,...
Map showing depth to water table, September 1976, and area inundated by the June 1975 flood, Helena Valley, Lewis and Clark County, Montana
Kathleen R. Wilke, M. V. Johnson
1978, Open-File Report 78-110
Depth to water table, September 1976, and area inundated by the June 1975 flood in the Helena valley, Montana, are mapped on two sheets, Helena and East Helena 7.5-minute quadrangles, at scale 1:48,000. Depth to water table was mapped using water-level measurements from existing shallow observation wells and selected domestic...
