Compaction rates of sediments or volcaniclastic material are needed to reconstruct original thickness of a bed, which in turn is required to reconstruct subsidence rates, sea-level rise, or in the case of volcanielastic, the location or direction of the eruption site. The knowledge of compaction rates can also aid in the reconstruction of deformed fossils. The known shape of deformed fossils can allow the determination of the compaction they experienced. Here we report the compaction rate in an early Permian volcanic tuff from wuda, Inner Mongolia, determined from the deformation of standing tree fern stems of known anatomy. The compaction rate has been found to be 0.56 in this case, indicating that 44% of original thickness remains.

Relationship Between Coal Facies and Washability of High-Sulfur Coal

引用

International Journal of Mining Science and Technology 2000年第1期21卷 75-78页

作者：代世峰唐跃刚张卫彪焦方立马凤学李宝春

The petrographic characteristics and facies of the high-sulfur coal (No. 9 coal seam) in wuda coalfield were analyzed and the washability of stratified coal samples formed in the different coal facies was discussed using the density component method of coal petrology. The results show that the washability of different stratified coal samples in tbe same coal facies is similar, and the accumulating environment of peat swamp controlls the contents and the occurrence of minerals, and thus controll the coal washability. The washability or the stratified coal formed in high peat swamp is better than that formed in low peat swamp.
