Mineral resources and conservation in Texas
(University of Texas at Austin. Bureau of Economic Geology, 1970) Flawn, Peter Tyrell
The conservation movement has grown enormously in strength and breadth during the last decade as a result of widespread concern about natural resources and the quality of the environment. The Federal leadership broadened the definition of conservation to applied ecology and thereby put a meaning into the word that went far beyond its original sense. Conservation now includes all of the physical, social, and legal problems attendant on use of the land. The inclusion of a wide variety of environmental problems under the umbrella of conservation caused a great deal of pushing and shoving of traditional "conservationists" to make way for the new "environmentalists." Broadening of the conservation movement to a total-environment movement has brought many new people into it--scientists, engineers, economists, geographers, and ecologists--people that are professionally concerned with the environment on a working-day basis.
Mineral resources of south Texas, region served through the Port of Corpus Christi
(University of Texas at Austin. Bureau of Economic Geology, 1962) Maxwell, Ross A.
This report is a compilation of all available data on mineral resources (exclusive of oil and gas) in 39 south Texas counties. Information from published and unpublished sources was checked and supplemented by field investigations. The study was carried out in cooperation with the Corpus Christi Chamber of Commerce to provide an inventory of mineral resources in the trade area served through the Port of Corpus Christi.The rock and mineral resources in the northwestern part of the trade area in and associated with Cretaceous formations include high-calcium limestone, Portland cement materials, clay for structural clay products, asphaltic limestone, gravel, and limited amounts of low-grade manganese, barite, celestite, and guano. The principal mineral resources in the Tertiary and Quaternary formations of the Gulf Coastal Plain are uranium minerals, industrial sand, gravel, bleaching clay, drilling mud, expanded clay aggregate, structural clay products materials, caliche for road surfacing, crushed stone, peat, lignite, bituminous and cannel coal, salt, gypsum, sulfur, and oyster shell.
Mineral resources of the Colorado River Industrial Development Association area
(University of Texas at Austin. Bureau of Economic Geology, 1958) Dietrich, John W.
The Colorado River Industrial Development Association area consists of ten counties [Bastrop, Blanco, Burnet, Colorado, Fayette, Llano, Matagorda, San Saba, Travis, and Wharton counties] in the lower watershed of Colorado River in Texas. The rocks exposed in the upriver part of the area include Precambrian metamorphic and igneous rocks and Paleozoic and Lower Cretaceous sedimentary rocks. In the Austin region Upper Cretaceous sedimentary rocks are exposed. In the downstream part of the area the rocks are of Tertiary and Quaternary ages. The principal mineral resource materials are industrial rocks and minerals. In the part of the area from Austin upstream, the most important materials are building stone, chemical limestone and dolomite, cement materials, graphite, soapstone, serpentine, vermiculite, and iron ore. From Austin downstream, the most important materials are sand and gravel, bleaching clay, burning clay, lignite, salt, sulfur, and oyster shell. There are small or low-grade deposits of many other materials, especially in the upriver region.

Rock and mineral resources of East Texas
(University of Texas at Austin. Bureau of Economic Geology, 1965) Fisher, W. L. (William Lawrence), 1932-
In the past 100 years, more than 100 names have been used to designate parts or all of the outcropping Midway and Wilcox rocks in the Gulf Coastal Plain; less than half of these names are used currently by Coastal Plain geologists, and the validity of some of the remaining named rock units has been questioned in certain recent studies. A compilation of these names shows the development of present-day terminology. Owing to the noncoincidence of certain time-rock and rock units within the Midway-Wilcox section, time, time-rock, and rock terms often have been used indiscriminately, resulting in a terminology that is in part confusing and misleading. Because of the importance and significance of this part of the Gulf Coastal Plain section, a proper definition of time-rock and rock units is desirable; a conceptual distinction of these units is imperative. One logical arrangement is to use the terms Midway and Wilcox strictly as rock terms (group) and to use the terms Paleocene and Eocene as time terms (age). If specific time-rock terms (stage) are needed, such a term as Sabinian is available.

Texas mineral resources: problems and predictions
(University of Texas at Austin. Bureau of Economic Geology, 1965) Flawn, Peter Tyrell
When a reference is made to the mineral resources of Texas, most people think of oil and gas, and some few also of sulfur. And, of course, it is true that of the whopping $4.4 billion dollars' worth of minerals produced in Texas in 1963, 92% was oil, gas, and natural gas liquids. In 1963, for the 29th year, Texas led the Nation as a producer of minerals. Value of mineral products was twice the value of agricultural products, equal to the value of manufactured products, and equal to about one-half the value of all retail trade. It is clear that the State has a mineral-oriented economy; it is true also that the mineral industry is distributed broadly throughout the State and not concentrated in several giant oil fields or very large mines--241 of 254 counties reported mineral production in 1963. But in addition to oil and gas, Texas produced 22 other minerals last year valued at $361.7 million dollars. There are indeed many States which would happily settle for this 8 percent of Texas' mineral production. Significantly, this is the segment of Texas' mineral industry growing most rapidly, and it is the segment that will continue to grow.
Texas minerals: trends in production
(University of Texas at Austin. Bureau of Economic Geology, 1965) Fisher, W. L. (William Lawrence), 1932-
Minerals play a vital role in the economy of an industrial State. In Texas, where annual production of minerals currently amounts to more than $4. 5 billion--twice the value of agricultural products, equal the value of manufactured products, and equal to half the value of all retail trade--mineral production is the principal part of the State's economic foundation. Analyses of past production trends and economic factors allow predictions of future trends in this vital and important segment of the Texas economy. Included herein are production graphs and brief annotations of production trends of principal or representative Texas mineral commodities. Period considered is 1950 through 1964, a period embracing significant post-war developments in the State and National economy.
