Volcaniclastic sands at Sites 1173 and 1174, Quartzose sands at Sites 1175 and 1176, and Sedimenticlastic sandstones at Site 1178. Sands and sandstones from Site 1177 include both quartz-rich and sedimenticlastic types. Apart from Site 1177 there were minimal vertical variations in mineral and clast types in sand and sandstone at Leg 190 sites.
First, quartz is very important rock-forming mineral. It occurs in many igneous rocks, especially granite.It is also very common component of many metamorphic rocks (quartzite containing little else than quartz).And finally, quartz is a major component of sedimentary rocks, especially sandstone.As these rocks weather and disintegrate, quartz crystals are liberated as sand grains.
The composition of these sand samples is highly variable. The most common constituents of heavy mineral sands are garnet, magnetite, ilmenite, and epidote. Most heavy mineral sand samples contain quartz as well, but it is not as important as usual. Beach sand from Calvert Cliffs State Park, Soloman Islands, Maryland.
Example quartz sands, volcanic sands, mineral sands, and more. Common components of abiogenic sand are Dark lava flows are basalt. As basalt weather and erode, it forms dull black, gray, or brownish-red grains of gravel and sand. Feldspar is a rock-forming mineral occurring as colorless or pink crystals.

Such sands are present in areas from the coast to a hundred miles or more inland beneath soil ...
Feb 22, 2011 These sands may be called lithic sands and they may contain a huge variety of rock fragments (granite, basalt, sandstone, limestone etc). Lithic sands from the British coastline (most lithic sands have dark color) Heavy mineral sands contain those minerals with specific weight higher than 2.9 g/cm. Due to their stable composition in time, the ...
Epidote is a metamorphic mineral. By saying that I mean that this mineral as a sand grain is a weathering product of metamorphic rocks. Tourmaline. Tourmaline is formed in granitic pegmatites. It is a relatively rare mineral in rocks but pretty common in the heavy mineral fraction of most sand samples because of its extreme resistance to weathering.
Rutile crystal in quartz. R23670. Source Geoscience Australia. Most sand on the beach consists of grains of the mineral quartz (SiO 2 ). Mineral sands are old beach, river or dune sands that contain concentrations of the important minerals, rutile, ilmenite, zircon and monazite. These heavy minerals have a relative density of between 4 and 5.5 g/cm 3 and are much heavier than common sand minerals
