Select lacustrine and marine depositional settings show a spectrum of styles of carbonate deposition and illustrate the types of carbonates, with an emphasis on microbialites and tufa, to be expected in early rift settings. Early rift lake examples examined in this review article are all from East Africa: Lakes Turkana, Bogoria, Natron and Magadi, Manyara, and Tanganyika. Other lake examples include four from the western United States (Great Salt Lake and high lake level Lake Bonneville, Mono Lake and high lake level Russell Lake, Pyramid Lake and high lake level Lake Lahontan, and Searles Lake) and two from Australia (Lakes Clifton and Thetis). Marine basin examples are the Hamelin Pool part of Shark Bay from Australia (marginal marine) and the Red Sea (marine rift).

Landsat images and digital elevation models for each example are used to delineate present and past lake-basin margins based on published lake-level elevations, and for some examples, the shorelines representing different lake levels can be compared to evaluate how changes in size, shape, and lake configuration might have impacted carbonate development. The early rift lakes show a range of characteristics to be expected in lacustrine settings during the earliest stages of continental extension and rifting, whereas the Red Sea shows well advanced rifting with marine incursion and reef–skeletal sand development. Collectively, the lacustrine examples show a wide range of sizes, with several of them being large enough that they could produce carbonate deposits of potential economic interest. Three of the areas—Great Salt Lake and high lake level Lake Bonneville, Pyramid Lake and high lake level Lake Lahontan, and the Red Sea—are exceedingly complex in that they illustrate a large degree of potential depositional facies heterogeneity because of their size, irregular pattern, and connectivity of subbasins within the overall basin outline.

Recent debates have flared in the western United States over federal versus state ownership of public lands. Bills concerning the transfer of some public lands to states have been introduced in the U.S. Congress and many western state legislatures, though none have become law.

In the interest of continuing my theme of “Spreading the Word” about AAPG’s Division of Professional Affairs, here’s an update on some exciting events organized by DPA members for the spring of 2016. Many of you may be familiar with the Playmaker concept, as we have previously held five very successful events.

Houston, Texas, United States
6 April 2017

In Conjunction with AAPG 2017 Annual Convention & Exhibition (ACE)
This field trip focuses on the late Quaternary depositional systems of the upper Texas coast, including the Brazos River and its wave-dominated delta, the Oyster Creek meanderbelt, Follets Island, the San Luis Pass tidal delta, and Galveston Island. The trip will emphasize the physical processes associated with shaping these various depositional environments, and will discuss the stratigraphic occurrence of sand bodies associated with these coastal systems. There will be a focus on linking physical processes to the geological record, and also describing the sequence stratigraphic framework of the upper Texas coastal systems.

The Spindletop trip takes participants to the site of the “Lucas Gusher,” where on January 10th, 1901 in Beaumont, Texas, 100,000 barrels per day gushed from a salt dome formation. This discovery changed the economy of Texas and helped to usher in the modern petroleum age. The first six gushers in the Spindletop field produced more oil per day than the combined production of all the other producing fields in the world. The Lucas geyser, found at a depth of 1,139 feet, blew a stream of oil over 100 feet high until it was capped nine days later. Lucas and the Hamills finally controlled the geyser on January 19, when a huge pool of oil surrounded it. By that time, throngs of oilmen, speculators, and onlookers had already transformed the city of Beaumont. A new age was born.
