Sulfur content in the burned oil shale was on average 1.6% . Most of the released sulfur is expected to combine with free CaO and settle back to ash when oil shale is burnt, but some of it will oxidize first to SO 2 and further to SO 3, leading to formation of sulfuric acid, which can nucleate or condense to form particulate sulfate.
These fine-grained rocks consist of microscopic (<0.062 mm in longest dimension) clay and quartz grains. Lithic fragments are absent. 7.70 The Marcellus Shale, Pennsylvania. We call the finest grained rocks shale if they exhibit fissility. Fissility, the ability to cleave into very thin layers, results from parallel alignment of clay grains.
