Faulted southeastern side of Svyatoy Nos peninsula, Lake Baikal – active faulting shown by faceted spurs. Artificial rendering of the Albertine Rift showing four of its rift lakes A rift lake is a lake formed as a result of subsidence related to movement on faults within a rift zone, an area of extensional tectonics in the continental crust .
Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [2] The general distinction between pools/ponds and lakes is vague, but Brown [1] states that ponds and pools have their entire bottom surfaces exposed to light, while lakes do not. In addition, some ...
The Rift Valley lakes are a series of lakes in the East African Rift valley that runs through eastern Africa from Ethiopia in the north to Malawi in the south, and includes the African Great Lakes in the south. These include some of the world's oldest lakes, deepest lakes, largest lakes by area, and largest lakes by volume.
There are no known bioluminescent stygobites to date, despite this adaptation's popularity in other dark systems. [26] Outside of light availability, there are a wide variety of geochemical parameters that affect the biology and ecology within these systems. Possibly the most notable and universal in these systems is the strong halocline.
Lacustrine deposits have gained more attention recently due to containing valuable source rocks of oil, coal, and uranium. Lacustrine deposits generally provide productive mining conditions but can prove challenging when underground mines are attempted due to the poor shear strength of clays and silts as well as the amount of moisture often locked in the layers due to a low permeability ...
Lake Nipissing; 8,400 – 5,500 YBP formed as the water bodies in the Superior and Huron basins merged across Sault Ste. Marie around 8,400 YBP and then merged with the Michigan basin around 7,800. [1] Lake Stanley-Hough; 8,700 YBP, the water levels had risen to connect both Lake Stanley and Lake Hough into a single body of water. [1]
Tectonic lakes are lakes formed by the deformation and resulting lateral and vertical movements of the Earth's crust. These movements include faulting, tilting, folding, and warping. Some of the largest lakes on Earth are rift lakes occupying rift valleys, e.g. Central African Rift lakes and Lake Baikal.
These three beds preserve the early sedimentation of Lake Malawi. The water surface was probably 300 meters higher above sea level than it is presently, confined to an area a quarter of its present size in the north. Geologists believe that down-faulting allowed the lake water to flow to lower elevations, extending to Cape Maclear Peninsula ...
