About relation between magmatism in alkaline rift and saline deposits in rift, many investigations have been done by Michael and Garson (1984) but relation between alkaline magmatism and saline deposits are not clarified, red sea, Mediterranean Sea, Atlantic Ocean and rift to east Africa are four samples for these three phenomena. Alkaline magmatism is rich from CO2, K, Na, Ca, SO2 and H2S and it saturates water separately.
If sedimentary basin has energy with displacement in water column and it is increased by underground streams or waves and … by increase in publication velocity of ions. If environment energy is low, saline water is concentrated and displacement is done. High density of saline water results in not extruding of water column and hence sedimentation of sulfate salts sedimentation is started.
Deficit cycles and recurrent sedimentation which is seen in nature result from change in magmatic ions in large scale. Depth of sedimentary basin is difficult that evaporate model can not explain that. Aggregation of red layers, black shale with sulfurs aggregation of saline sulfates to rift zone is related and its genesis is explained by new model (volcanism model).
