Padiiset's Statue or Pateese's Statue, [1] also described as the Statue of a vizier usurped by Padiiset, is a basalt statue found in 1894 in an unknown location in the Egyptian delta [2] [3] which includes an inscription referring to trade between Canaan and the Peleset (Philistines) and Ancient Egypt during the Third Intermediate Period.
Lava delta of Ponta dos Biscoitos, Sant Cruz das Ribeiras, Pico Island Lava deltas , similar to river deltas , form wherever sufficient sub-aerial flows of lava enter standing bodies of water. The lava cools and breaks up as it encounters the water, with the resulting fragments filling in the adjacent seabed topography such that the flow can ...
Basalt columns seen on Porto Santo Island, Portugal. Columnar jointing of volcanic rocks exists in many places on Earth. Perhaps the most famous basalt lava flow in the world is the Giant's Causeway in Northern Ireland, in which the vertical joints form polygonal columns and give the impression of having been artificially constructed.
Abyssal (or submarine) fans are formed from turbidity currents. These currents begin when a geologic activity pushes sediments over the edge of a continental shelf and down the continental slope, creating an underwater landslide.
A major one forms the eastern side of Carsaig Bay whilst a couple of smaller ones occur further west. Multiple slips affect the coast between Rubha a’ Ghearrain and Rubha na-Uamha on the Ardmeanach peninsula, notably at Balmeanach and ‘The Wilderness’. Each has occurred where basalt lavas overlie incompetent Mesozoic sedimentary rocks. [16]
Lapilli or volcanic cinders – between 2 and 64 mm (0.08 and 2.5 inches) in diameter Volcanic bombs or volcanic blocks – larger than 64 mm (2.5 inches) in diameter The use of tephra layers, which bear their own unique chemistry and character, as temporal marker horizons in archaeological and geological sites, is known as tephrochronology .
Eruptions of basalt magma typically produce elongate lava flows, as well as build cinder cones (piles of small frothy lava fragments or 'cinders') around volcanic vents. [4] Basaltic volcanism in the Lassen volcanic area occurs mainly along chains of vents aligned in a north or northwest direction, parallel to regional faults.
In the sediments between the basalt layers there are in places marks left by stems and leaves along with carbonated plant material. These sediments, however, are not the only ones that carry plant remains, among the thickest sediments among the basaltic formations there are finely grained silt and clay sediments formed in basins that once were ...
