TL;DR: In the Danakil Alps of coastal Eritrea as mentioned in this paper, an asymmetrically subsided block of old sialic crust has been uplifted along the Ethiopian rift and is covered by an evaporite-basalt veneer.
Abstract: Mesozoic and Precambrian rocks are exposed in the Danakil Alps of coastal Eritrea, but the Danakil Depression between the Alps and the Ethiopian plateau is covered by Tertiary-Quaternary rocks. The physiography, structural geology, regional stratigraphy and evaporite lithof acies distribution of this area all suggest that it is underlain by an asymmetrically subsided block of old sialic crust. The western edge of this block has subsided deeply along the Ethiopian rift and is covered, in the Danakil Depression, by an evaporite-basalt veneer, but its eastern edge has been uplifted as the Danakil Alps. These are bounded on the east by a rift escarpment facing the Red Sea. Although geologic data here is sparse compared to the Danakil region, certain features suggest that a similar asymmetrically subsided block of older sialic rocks, with an evaporite-basalt veneer, may also lie beneath much of the Red Sea. This tectonic evolution apparently commenced in Miocene time with rifting near the centre of an earlier Mesozoic-Paleogene sedimentary basin. Uplift along this central rift caused tensional failure along a secondarily induced rift to the west, and east-side-down subsidence along this structure formed the asymmetrically subsided block. There were apparently two successive cycles of this tectonic activity. The earlier, of Miocene age, formed the easterly (Red Sea) block with a thicker veneer of older evaporitebasalt, and the later, of Plio-Pleistocene age formed the westerly (Danakil) block with a thinner veneer of younger evaporite-basalt. The separation of Arabia from Ethiopia across the southern Red Sea would thus be relatively minor, presumably represented by the width of the Red Sea’s axial trough plus a few kilometres across each of the Danakil Alp and Ethiopian rifts. Similar tectonic developments may accompany initial rifting and separation in the development of ocean basins by seafloor spreading, and might explain why oceans like the Atlantic, that have apparently developed in this manner, are fringed by shallow continental shelves with thick evaporite sequences and steep walled submarine canyons.

24 Jun 1992TL;DR: In this article, heavy oil is hydrotreated by processing with hydrogen in the presence of a catalyst composition comprising an activated carbon component having a specified range of pore volume distribution and average pore diameter, a molybdenum or tungsten component and a cobalt or nickel component to reduce the content of nickel and vanadium therein and to achieve demetallation and conversion of the carbon residue for producing a lighter oil.

TL;DR: In this article, a series of traveling heater experiments was performed on the crystal growth of CdTe from Te solution, and it was shown that acceleration rotation can increase the growth rate by a factor of 2, while the natural convection currents generated under the particular experimental conditions are already very strong.

21 Aug 1984TL;DR: A fluid catalytic cracking (FCC) apparatus and process comprising a reactor riser zone, a primary and a secondary cyclones, connected in series to the riser, and a stripping zone is described in this article.
Abstract: A fluid catalytic cracking (FCC) apparatus and process comprising a reactor riser zone, a primary and a secondary cyclones, connected in series to the riser zone, and a stripping zone. The riser zone, the primary and the secondary cyclones, and the stripping zone, are placed within a single reactor vessel. The primary cyclone is connected to the reactor riser zone by an enclosed conduit which prevents random post-riser thermal cracking of the hydrocarbons after they exit the reactor riser zone. The conduit contains a trickle valve, or other means, to accommodate sudden increased surges of flow of the hydrocarbons and catalyst mixture.
