...D. M. Collingwood; R. E. Rettger ABSTRACT The Lytton Springs oil field is located in the northern part of Caldwell County, Texas. It covers an area approximately 1 1 2 miles in diameter. The discovery well was brought in on March 13, 1925, at a depth of 1,350 feet and the following March there were...

... chalk is estimated to be approximately 1,500 feet, although here, as in the Lytton Springs serpentine field, it is probable that some of the upper part of the chalk has been displaced by serpentine. Data from the following wells, designated by serial letter on the maps and profile, were used...

With the perfection of the magnetometer, attempts were made to locate buried serpentine masses similar to those at Thrall, Lytton Springs, and Dale, where commercial production had been found in altered basic rocks, particularly in the horizons of the Austin and Taylor formations of Upper Cretaceous age...

However, certain characteristics indicate that the rocks of each field vary somewhat in details of structure and origin. The character of the rock has been determined by a petrographic study...
