Information and translations of overlying in the most comprehensive dictionary definitions resource on the web. Overlying material is often unconsolidated rock, which is made up of loose particle s. Bedrock can extend hundreds of meters below the surface of the Earth, toward the base of Earth's crust. A reduction in stress occurs when rocks previously buried deeply are exposed due to erosion of overlying rocks, or when ice sheets that bury rocks melt. Intrusive igneous rocks (e.g. Stress caused these rocks to fracture. Since the rock cannot move, it cannot deform. When a cap rock, an overlying laye r of imperme able rock, exi sts above. A deeply buried rock is pushed down by the weight of all the material above it. Four types of stresses act on materials. [...] and prevent the upward escape of the oil and natural gas. In deeply stratified rocks, removal of overlying strata due to weathering gives rise to compression-tension forces that may cause regular and irregular jointing of various types. This constant pressure from overlying sediments and water compacts the sediments until they form into a solid rock mass. granite) are formed deep beneath the Earth's surface. energy4me.org. cordis Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock. A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments. The outer parts of the rocks then tend to expand. Once the overlying rock layers were eroded and the Navajo Sandstone revealed, weathering of the sandstone exposed the hard, weather-resistant iron concretions, many of which are amassed in large groups on the surface. * T4a: The tumor has invaded the anterior orbit, anterior cranial fossa, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Response Analysis of the Free Field under Fault Movements, Application of DICM on Similar Material Simulation Experiment for Rock-Like Materials, An Approach to the differential erosion at the upper contact of the Jhelum Group across the Salt Range and Trans-Indus ranges and a comparative study of the Post-Cambrian Rocks between Upper Indus Basin and Peshawar Basin, Mechanism of rigid overlaying of carboniferous strata failure in face mining in the case of a multiseams deposit, Malignant ethmoid sinus tumor masquerading as chronic ethmoid sinusitis. ‘North of it lies a more permeable medium in the form of sand and gravel overlying silty clay with gravel.’.
