The following document is a collection of reports on the studies of the early Mesozoic basins of the Eastern United States. The reports are divided into four sections: reports that study the sedimentary rocks of the basins, studies of related to Jurassic igneous rocks, studies related to the geophysics, structure, and tectonics of the basins, and studies related to the mineral resources.

From abstract: A complex Neogene history characterizes the offshore Santa Maria basin and the northwest margin of the western Transverse Ranges, California. This history includes the transition from subduction to a transtensional and then transpressional plate boundary, including about 900 of clockwise rotation of the western Transverse Ranges. This report uses seismic reflection data to document the geometry of structures that accommodated this deformation and offshore well data to date and correlate the sediments which were affected by the different tectonic episodes.

Abstract: The U.S. Geological Survey and the Corporación Venezolana de Guayana, Técnica Minera, C.A., conducted a cooperative mapping, exploration, and mineral resource estimation study in Venezuela from 1987 to 1992. The work was conducted in the Venezuelan Guayana Shield, an Archean to Early and Middle Proterozoic craton in southern and eastern Venezuela of almost 415,000 km2 that is mostly covered by jungle and savanna. Results obtained from this project contribute a new understanding of the geology and evolution of the Venezuelan Guayana Shield and the nature of its mineral occurrences. Personnel from Técnica Minera, C.A., were trained both in the field and in the office to conduct modern mineral exploration and geologic mapping and research programs. This five-year project was supported financially by the Corporación Venezolana de Guayana.

The following report is a mineral resource assessment of Coronado National Forest of southeastern Arizona and southwestern New Mexico, formed by geologic, geochemical, and geophysical data.

A report about nomenclature related to planets in the solar system. It contains detailed information about all names of topographic and albedo features on planets and satellites.

A report about the natural gas drilling frontier in deep sedimentary basins. Papers presented here are intended to introduce the petroleum community to a set of geologic tools that may be used to predict deep undiscovered natural gas accumulations.
