geography of pakistan,the rocks found in pakistan can be classified into three major groups, viz. the igneous rocks, the sedimentary rocks and the metamorphic rocks. in the himalayan regions, the common rock types are metamorphic which are gneisses, schist, slates and phyllites with some quartzite and marble. in the northern part of indus plain, between sargodha and.metamorphic rocks: a classification and glossary of terms,it presents a complete nomenclature of metamorphic rocks, with a comprehensive glossary of definitions, sources and etymology of over 1200 terms, and a list of mineral abbreviations. twelve multi-authored sections explain how to derive the correct names for metamorphic rocks and processes, and discuss the rationale behind the more important terms..metamorphic, magmatic, and tectonic evolution of the,m 4 (<5 ma) is a syntectonic retrogressive metamorphism along the hanging wall of the main karakoram thrust—a breakback thrust responsible for the recent uplift of the karakoram. structural culminations of midcrustal rocks occur in the k2 and broad peak areas within carboniferous-lower cretaceous sediments of the gasherbrum range..regional metamorphism • geolearning • department of earth,pakistan. image credit: dorothee mertmann. regional metamorphism includes any metamorphic process that occurs over a large region. it is therefore the most widespread and common type of metamorphism. there are three basic types of regional metamorphism, namely burial, ocean-ridge and the orogenic regional metamorphism..
13. marble • marble is the coarse grained rock composed of interlocking calcite crystals forms when limestone recrystallizes during metamorphism if the parent rock is the dolomite the recrystal rock is the dolomitic marble • marble is however highly susceptible to chemical weathering. 14..metamorphic rocks presentation,metamorphic rocks presentation - free download as powerpoint presentation (.ppt / .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. a thorough presentation on characteristics and description of all main types of metamorphic rocks..metamorphic rocks - an overview,3.1.2 metamorphic rock. metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism. the protolith is subjected to heat and pressure causing profound physical and chemical change. the protolith may be sedimentary rock, igneous rock, or another (older) metamorphic rock.
metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich.geology of pakistan,3.4 cenozoic sedimentary rocks 101 3.41 palaeogene 103 3.42 the palaeogene sequence in the west pakistan foldbelt 105 3.43 neogene 114 3.44 quaternary 118 4. igneous and metamorphic rocks (fail ahmad shams) 125 4.1 igneous and metamorphic rocks of the tethyan belt 125 4.11 indo-pakistan plate 125 4.111 south of the main mantle thrust (mmt) zone 125.metamorphic rock worksheets,metamorphic rock. showing top 8 worksheets in the category - metamorphic rock. some of the worksheets displayed are metamorphic rock work, reading comprehension work and kids fable, rocks and minerals, metamorphic rocks, rock work, rocking the rock cycle part 1 of 3, rock cycle diagram, name types of rocks.
in gen- eral, the northern pakistan is home to medium and high-grade metamorphic rocks; however, the sub-lesser himalayas (i.e., himalayan hinterland) exhibit a huge swath of low grade me- tamorphic rocks. the peshawar basin is part of the lesser himalayas..metamorphic temperature investigation of coexisting,read 'metamorphic temperature investigation of coexisting calcite and dolomite marble––examples from nikani ghar marble and nowshera formation, peshawar basin, pakistan, journal of earth science' on deepdyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips..learning geology: 3d geological model of pakistan,it is a 3d geological model of pakistan that shows mainly tectonic division of mountain ranges of pakistan. the model demonstrates the major/famous deposits of pakistan like petroleum, minerals/gemstones, uranium, coal including other geographical features like dams and rivers. it is a non-working model (size: 5×6 ft approximately) supported
