Volume 25, Issue 99 , June 2016, , Pages 271-280

https://doi.org/10.22071/gsj.2016.40918

Abstract
  Gheshlagh district contains coal deposits in a large syncline in Shemshak group sediments in East Alborz. To determine the palaeoenvironmental setting of the coal deposits based on organic and mineral components, eleven samples from coal seams from four active mines are collected. Minerals such as quartz, ...  Read More
