This may be one of the reasons why precipitation of manganese oxides is remarkable on the surface of laterite at the Koh Ker monuments.
The reason is the precipitation of crystalline saturated methyl esters.
The pumping property of Turkish plateau which continuously attracts moist air from low latitude oceans can be another important reason for higher precipitation in summer.
The second reason is the precipitation as hematite Fe2O3, where the particles have a lower bandgap (2.1 eV) compared to TiO2 (3.2 eV) and promote bandgap narrowing by heterojunction between Fe2O3 and TiO2, enhancing the absorption of visible light [8, 26, 36].
Volcanic eruption of Mt. Pinatubo (June 1991) and Mt. Hudson (August 1991) could be the reason for the precipitation of Pb, Cd, Cu, Zn, and Se together with non-sea salt sulfates in the austral spring at Asuka Station.
The major reason being that the precipitation is a major component of water balance (Beeson et al. 2011).
The presence of Mo in AISI 316Ti stainless steel reduces chromium-rich carbide precipitation; the reason is that Mo increases the stability of titanium carbides and tends to replace chromium in the formation of carbides and intermetallic compounds, thus reducing the risks of chromium-depletion.
The reasons are the small time precipitation of Cd at its relatively small (compared to other samples) excess in the parental solution (2 1).
The reason for the temporary lag in precipitation is unknown.
