“…Laboratory tests were not carried out to determine the Silali basin's age because this had previously been reported to be about 62-64KA [2,11]. The ages of most of the ETICs on the earth's surface are known thus, it is necessary to also document the age of the Silali basin because there is a coincidence between the ages of Hypervelocity Impacts (HVIs) crater formation and major events on the earth's surface.…”

“…Volcanic eruptions in Silali occurred during different times and some of the later ones, according to the authors, resulted in an inward collapse of the shield summit, owing to the lateral drainage of magma from beneath the volcanic shield. According to the scholars, these are the eruptions that led to the formation of the caldera around 66-62KA [2,11]. The existence of a volcanic shield in Silali before the ETIC formed is favoured by the following incidences: i.…”

“…The whole of the Silali volcano has an enveloping of an alluvial apron (sediments) [11]. Thus, the presence of massive rough dust deposition (or 'apron of alluvium') on the flanks of Silali basin, instead of magma deposition, is evidence that Silali basin may be a product of an extra-terrestrial impact rather than volcanicity [7].…”

“…[2] [11]. Though access to the black hills was not possible due to insecurity, owing to marauding cattle rustlers, the description of the trachyte cones suggest an impact origin; first because the glasses mentioned are black to blackish-brown in colour, just like tektites in other ETICs.…”

Certain rocks, rock minerals and rock formations have come to be associated with ETICs (Extra-terrestrial Impact Craters). An extra-terrestrial impact crater is a crater that is formed by an extra-terrestrial impact event whereby a heavenly body (a meteor, comet, or asteroid) hits the earth’s surface and creates a crater; before it cools on the earth’s surface as a meteorite or completely gets squashed by the thermodynamics of space transit. The crater created can be dry or filled with water and may be a simple crater or a complex one, also denoted as a basin. The objective of this paper is to describe the geology of the Silali basin as an Extra-Terrestrial Impact Crater (ETIC), highlight the importance of some of its ETIC rocks and explain the formation of the Silali basin resulting from extra-terrestrial impact. Data was collected through field observation, remote sensing, analysis of past geographical and geological studies, interviewing and laboratory analysis. Information has been presented in the form of analyzed satellite images, pictures, tables, and maps. Notably, this is the first study on extra-terrestrial impact cratering (ETIC) in Kenya. Consequently, the Silali basin, as an ETIC, and its environs, is a virgin field for further scientific research.
