Study of diagenitic processes and surface texture of the oldest river terrace deposits in Shirqat area- northern Iraq

Abstract

The recent project deals with the diagenitic processes and surface textures of the oldest river terraces deposits in Shirqat area, the diagenitic processes compiled with Cementation, Compaction and Dissolution. The carbonate minerals represent the cementic materials while the point contact compaction represent the degree of compaction in this sediments because the small thickness of the overburden sediments and the secondary effects of differential dissolution. The surface texture is very developed in the large size of sediment included pebble, cobble and boulders which form very developed surface texture formed order and disorder forms as well as smooth surface texture.
