Unreported anywhere are the massive petroleum concessions and exploration projects in Kenya’s remote Samburu and Turkana districts. (For $5000 apiece you can purchase reports like Petroleum Potential of Lake Turkana Area from international oil and gas consultants Beicip-Franlab.11) G.H.W.

Shallow salt domes in central Mississipi pierce Mesozoic formations hosting regionally extensive metal-rich brines. This association, coupled with the multiple fluid-migration pathways around salt domes, suggests that these brines were the source of Fe [iron] and base-metal sulfide, Sr [strontium], and Ba [barium] minerals in salt dome cap rocks. Fluid inclusions in barite and celestite indicate that the brines had a relatively constant average composition of approximately 200,000 mg/l total dissolved solids, which is similar to present-day oil field brines from central Mississippi. Geochemical reaction-path modeling indicates that the suite of observed cap rock minerals can be produced by alternating periods of biogenic SO4 reduction with inorganic anhydrite dissolution (or by mixing with seawater). Sulfide-rich portions of cap rock at Hazelhurst salt dome have molar Fe: Pb and Fe:Zn ratios similar to present-day oil field brines, indicating that mixing of brines with abundant amounts of H2S produced by biogenic SO4 reduction led to rapid precipitation of virtually all dissolved metals as relatively insoluble sulfide minerals.
Eugene Coste wrote:... The salt islands [salt domes] of Louisiana were described by Capt. Lucas in the transactions of the American Institute of Mining Engineers before his discovery of oil at Beaumont [Spindletop, 1901]. These so called islands, rising from 80 to 250 feet above the surrounding marshes of the Coast Pairie, are hills beneath layers of stratified clay and sand. They belong to the same group of topographic phenomena as Spindletop hill at Beaumont. By sinking through the super-structure of sand and clay Capt. Lucas located the salt bodies, and determined their horizontal extent, developing also the important fact that, though limited in diameter, they were of great depth, that of Jefferson Island having been penetrated for 2,100 feet without reaching bottom... The bodies of salt discovered beneath the hills of the Coast Prairie are of remarkable size, thickness and purity, notably those of Louisiana, and one discovered within the past few months at Damon's mound which, for its lower 700 feet, is pure rock salt with occasional traces of oil... It was Capt. Lucas who discovered the relation between the sulphuretted hydrogen fumaroles, gas springs, and sulphur incrustations at the surface and the bodies of subterranean oil; and it was his belief in this association that led him to seek for oil on Spindletop hill... The oil is closely associated with the mounds occuring on their slopes or summits... In some localities hot water has been struck below the oil... In the original Lucas well, the oil itself is hot... It had a temperature of over 110 F. The oil seems to occur not in any definite continuous stratum but in spots of many strata. Gas in immense quanities and frequently under such pressure as to wreck the wells, has been struck before reaching the oil. This has occurred several times at Spindletop, twice at Sour Lake, and once at Velasco, where the destructive effect was terrific. Sulphur and sulphuretted hydrogen gas occur in intimate association with the Beaumont oil. In fact, the oil itself is said to contain 1 to 2% of sulphur, and the fumes of sulphuretted hydrogen are strong in the vicinity of the wells... Underground bodies of sulphur associated with the oil by natural processes have been found in many localities. The Calcasieu section of Hilgard shows 540 feet in depth solid sulphur rock similar to that encountered at 1040 [feet] in the Beaumont well. At Damon's mound a bed of sulphur from 10 to 40 feet thick was encountered above the salt. Crystals of free sulphur also occur in the cap rock overlaying the Spindletop oil. Capt. Lucas found the sub-strata of the south eastern part of Belle Isle, above and down to the salt rock, were heavily impregnated with petroleum. Several calcareous strata containing sulphur were also encountered... The wells at Damon's mound encountered small flows of oil at depths of from 400 to 600 feet... At Keyser's mound, in the same county, about six miles north of Damon's and near the Brazos River, a flow of oil was struck at 400 feet... Still another interesting phenomenon is the occurrance of dolomite. The oil of Spindletop is said to occur in a cavernous mass of this material. At Big Hill, Jefferson county, which is one of the most conspicious mounds, the drill after going down 300 feet penetrated a mass of coarsely crystalline dolomite in which it continued to nearly 1375 feet. At 900 feet a small seep of oil was struck in the dolomites...

StalkingGoogle wrote:The conventional usage of the term "fault" is to describe areas that are earthquake-prone, for example the interstitial "fault" near New Madrid in the midwest US. These kinds of "faults" don't seem to be related to any cracks anywhere in the crust, which suggests a completely different picture of earthquakes than the "rubbing plates" model suggests.
Stanley B. Keith wrote:Evidence is mounting that the Earth is encircled by subtle necklaces of interconnecting, generally latitude-parallel faults [aka 'cracks']. Many major mineral and energy resource accumulations are located within or near the deeply penetrating fractures of these “cracks of the world.” Future exploration for large petroleum occurrences should emphasize the definition, regional distribution, and specific characteristics of the global crack system. Specific drill targets can be predicted by understanding the local structural setting and fluid flow pathways in lateral, as well as vertical conduits, detectable through patterns in the local geochemistry and geophysics.
Stanley B. Keith wrote:At a more local scale, introduction of magma and hydrothermal fluids into the global “crack system” commonly is coincident with kinematic activity in the faults [aka 'cracks']. Indeed, analysis of mineral and chemical fractionation patterns produced during sequential introductions of the hot fluids offers new tools for kinematic and dynamic analysis of the global-scale fracture system.

Stanley B. Keith wrote:Summary and Implications for Petroleum Resources
Future petroleum exploration should emphasize domains of reduced crust where deformation is associated with slab-tears and regional trans-current faulting [breaks in the crust] that are related to the global crack system in both continental and oceanic regions.
The tectonic and metallogenic analysis of Mexico revealed patterns of crustal oxidation state and a country-wide, west-northwest fracture system that offsets the inferred Cambrian craton edge some 3500 km westward from its position within the Chortis block of Central America. Furthermore, this fracture system integrates with oceanic fracture systems in both the Pacific and central Atlantic ocean basins and offsets both ridge systems in each ocean basin by similar amounts - 3500 km.

Stanley B. Keith wrote:Much of the world’s major energy resource accumulations seem to be associated with the deeply penetrating fractures of the cracks of the world. These global cracks control the ascension of magmatic and hydrothermal fluids from depth. Under reduced conditions these fluids may be hydrocarbon stable and could be responsible for fractionation of extensive amounts of hydrocarbon during cooling and deposition in low-pressure sites of the cracks of the world.
Future exploration for giant petroleum fields should emphasize the definition, regional distribution, and specific characteristics of the global crack system. Because of the lateral strike-slip kinematics that accompany emplacement of given hydrothermal fluid plumes, specific drill targets at occurrence sites will be lateral as well as vertical to known resource occurrences. For example, petroleum resources in the largest hydrothermal mineral deposit in the world, the Ghawar field of Saudi Arabia (Cantrell et al., 2002), may be related to deposition of‚ regional-scale hydrothermal dolomites in a north-northeast-trending dextral slip zone that is 175 miles long and 30 miles wide. This zone is but one element of the previously mentioned north-south segments in the global fracture system.
In conclusion, we believe that significant new energy and mineral resources remain to be discovered by integrating resource occurrences with studies of crustal oxidation state, crustal fluid generation, hydrothermal plume fractionation/zonation, deep cracks, and a globally interconnected fracture [breaks in the crust] system.
