Land and water resources have been analyzed in the Corpus Christi area--Aransas, Nueces, Refugio, and San Patricio Counties along the central Texas coast. The city and port of Corpus Christi compose the largest metropolitan center in the area.

Lignite is a rediscovered energy in Texas because lignite-produced energy is 3 to 7 times cheaper than intrastate natural gas. Production has risen from 18,000 short tons in 1950 to 14 million tons in 1976 and will exceed 50 million tons by 1985.

Lignite occurs in three Eocene stratigraphic units--the Wilcox Group, Yegua Formation, and Jackson Group--and in three ancient depositional systems-fluvial, deltaic, and strandplain/lagoonal.

Contributing about 25 percent of all the energy ever produced in the United States, Texas has for 50 years led the nation in energy production.

Papers in this volume were presented at the Gulf Coast Lignite Conference held in Austin, Texas, June 1976.
Papers were edited, in some cases extensively, and subjectively grouped by discipline, paralleling that of their presentation at the Conference.

The land surface in the Texas Coastal Zone is interlaced with active and potentially active surface faults. They are subtle features which are difficult to identify until they have caused damage to manmade structures. To date (1978), significant damage has resulted.

Tertiary strata of the Texas Gulf Coast comprise a number of terrigenous depositional wedges, some of which thicken abruptly at their downdip ends as a result of contemporaneous movement of growth faults and underlying salt.
