PROFESSOR OP GEOLOGY BAYLOR UNIVERSITY 1929-1934 Objectives of Geological Training at Baylor The training of a geologist in a university covers but a few years; his education continues throughout his active life. The purposes of training geologists at Baylor University are to provide a sound basis of understanding and to foster a truly geological point of view, both of which are essential for continued pro­ fessional growth. The staff considers geology to be unique among sciences since it is primarily a field science. All geologic research in­ cluding that done in laboratories must be firmly supported by field observations. The student is encouraged to develop an inquiring objective attitude and to examine critically all geological concepts and principles. The development of a mature and professional attitude toward geology and geological research is a principal concern of the department.

  • Late Cretaceous and Tertiary Burial History, Central Texas 143
    A Publication of the Gulf Coast Association of Geological Societies www.gcags.org L C T B H, C T Peter R. Rose 718 Yaupon Valley Rd., Austin, Texas 78746, U.S.A. ABSTRACT In Central Texas, the Balcones Fault Zone separates the Gulf Coastal Plain from the elevated Central Texas Platform, comprising the Hill Country, Llano Uplift, and Edwards Plateau provinces to the west and north. The youngest geologic for- mations common to both regions are of Albian and Cenomanian age, the thick, widespread Edwards Limestone, and the thin overlying Georgetown, Del Rio, Buda, and Eagle Ford–Boquillas formations. Younger Cretaceous and Tertiary formations that overlie the Edwards and associated formations on and beneath the Gulf Coastal Plain have no known counterparts to the west and north of the Balcones Fault Zone, owing mostly to subaerial erosion following Oligocene and Miocene uplift during Balcones faulting, and secondarily to updip stratigraphic thinning and pinchouts during the Late Cretaceous and Tertiary. This study attempts to reconstruct the burial history of the Central Texas Platform (once entirely covered by carbonates of the thick Edwards Group and thin Buda Limestone), based mostly on indirect geological evidence: (1) Regional geologic maps showing structure, isopachs and lithofacies; (2) Regional stratigraphic analysis of the Edwards Limestone and associated formations demonstrating that the Central Texas Platform was a topographic high surrounded by gentle clinoform slopes into peripheral depositional areas; (3) Analysis and projection

  • Geology of the Balcones Fault Zone Along the Growth Corridor of San Antonio, Boerne, Wimberley, and New Braunfels, South-Central Texas
    Geology of the Balcones Fault Zone along the Growth Corridor of San Antonio, Boerne, Wimberley, and New Braunfels, South-Central Texas Edward W. Collins Bureau of Economic Geology, The University of Texas at Austin, University Station, Box X, Austin, TX 78713-7508 Extended Abstract The south-central Texas region that encompasses San Antonio, Boerne, Wimberley, and New Braunfels and adjacent areas west of San Antonio and northeast of New Braunfels is undergoing rapid urban growth. It lies within part of the recharge zone of the Edwards aquifer and includes a complex part of the Balcones Fault Zone (Fig. 1). The geology of this region is important to geologists and other professionals involved in planning land use, designing construction projects, and studying the Edwards aquifer. Recharge of the aquifer may be locally enhanced at karst features, faults, and joints. Faulted aquifer strata partly influence regional ground-water flow, and faults locally juxtapose strata having different physical properties, creating potential construction/foundation problems. Geologic maps are some of the most basic and useful sources of information for this geologically critical area of Central Texas. In this study, maps (scale 1:24,000) were prepared for a >1,250 mi2 region; additional mapping west of San Antonio and Boerne is ongoing. Maps have been interpreted using standard field mapping techniques and studying aerial photographs. Compilation and field verification of existing geologic maps of various scales aided map interpretation. This study benefited greatly from the many previous stratigraphic, structural, and mapping studies of the region. The Balcones Fault Zone, one of the main structural features of Central Texas, extends from near Del Rio east-northeastward to San Antonio, where the zone bends northward through New Braunfels, Austin, Georgetown, and Waco and continues toward Dallas.
