Size Analysis and Sediment Transportation Processes for Injana Formation in Borehole (KH8/9), NW Iraq

Textural grain-size analysis of Injana Formation in borehole (KH8/9) indicate the dominance of sandstones and siltstones. Cumulative frequency curves imply transporta-tion in different modes: suspension, saltation and rolling with the last of minor importance.
Textural attributes of the clastics showed them to be composed of fine sand, medium sorting with very positive skewed and being leptokurtic. The data point to the deposition by weak current and rapid accumulation. Bivariant plots of statistical parameters and applying of (C-M) diagram elucidated deposition in meandering river system.
