block faulting वाक्य

To the east and southeast, the Silver Peak Range borders the valley with no alluvial fans, and is the smaller massif probably block faulted from the White Mountains, and thru block faulting creating the smaller feeder valley on the White Mountains'southeast, ( the Furnace Creek Fault Zone ).
The geological process that gave rise to this structure has been attributed in one study to crustal down warping, block faulting, and mantle plume activity while another theory attributes it to continuous sand deposition and the natural process of sedimentation leading to the formation of a chain of barrier islands related to rising sea levels.
