Big Hill, Matagorda, is a characteristic Gulf Coast salt dome and has a distinct salt-dome mound, a subcircular salt core intruded into Tertiary sediments and a thick cap on the top of the salt. The cap contains an extensive and important deposit of sulphur. The cap is composed of (a) a “barren cap” of limestone above, (b) the sulphurbearing zone composed chiefly of limestone and grading below into (c) a thick deposit of barren anhydrite. The sulphur is secondary and later than the limestone and anhydrite. The sulphur is mined by the Frasch process in which superheated water is pumped down through a drilled well; the melted sulphur is collected at the bottom of the well and pumped to the surface by an air lift. A review is given of the possible reactions for the formation of the sulphur. On account of the lack of extensive drilling, little is known about flanks of the dome, a small amount of oil was produced in the early days, mostly from the top of the cap.

Geology of Salt Dome Oil Fields
Coming from an AAPG meeting in 1924, this volume strives to present a comprehensive picture of American salt domes, and to collect and record in permanent form the infirmation that has accumulated during twenty years of exploration for petroleum around the salt domes of the Gulf coastal plain. The plan for the volume included a brief, accurate description of each of the known salt domes. Although the list is not yet quite complete, the facts concerning a number of typical salt domes are presented with sufficient detail to portray +adequately the true nature of this remarkable type of geologic structure. Along with these descriptive papers, and based largely on the data contained in them, are several theoretical and interpretative studies, together, also, with some discussion of European salt domes.
