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 […]

Sapropel is a term used in marine geology to describe dark-colored sediments that are rich in organic matter. Sapropels events occurs periodically (around each 21000yr) and are specific to the Mediterranean sea. Organic carbon concentration in sapropels commonly exceeds 2% in weight. Their occurrence has been found to be related of the Earth’s orbital parameter.
Sediment can be consist of either mineral or fossil particles, and both types can be found in many places on the bottom of the sea. Classification of marine sedimentation :- The sedimentation can be subdivided on the basis of the size of the particles or on the basis of their mode of formation. Factors that
