It is usually considered to be the solid/solution interactive process occurring in contact with the atmosphere. In other words chemical weathering may be defined as that set of processes […]

MIS/OIS Marine Isotopic Stages

Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS) are alternating warm and cool periods in the Earth’s paleoclimate, deducted from oxygen isotope data derived from deep sea core samples. Working backwards from the present, MIS 1 in the scale, stages with even numbers have high levels of O18 and represents cold
