The identification of siderite in the cap rock of the recently discovered Carlos salt dome is believed to be the first recognition of this mineral in cap rock.
The Carlos dome is in the west-central part of Grimes County, Texas, almost due west of the town of Carlos, about 14 miles southeast of Bryan, and the same distance northwest of Navasota.
The nearest salt dome is Clay Creek, in Washington County, about 25 miles southwest.
The late E. D. Phillips found gas seeps and beds of paraffine dirt, and recommended that a block be taken in this area. Later geophysical investigation, both seismic and magnetic, confirmed the presence of a dome.
The first well, the Humble Oil and Refining Company's Temple-man No. 1, located in the G. W. Seaton Survey, was commenced October 1, 1933, and was completed November 6, 1933. The following is a log of this well.
