Abstract The Kawatuna area has a complex geological structure condition and is estimated to be weak zone for hydrothermal solutions rise then accumulate into deposits in the form of veins. Based on this, it makes this interesting study. This study aims determine its influence distribution veins area. method used surface mapping structures analysis. mapping, was found that composed schist rock u...

This study presents lithologic and petrogenetic investigation of bedded quartzite from Okemesi massive quartzites Ado-Ekiti in southwestern Nigeria. is extensive, thickly steeply dipping while hummocky, ferruginous, fractured, non-bedded. Analytical results reveal average SiO2 (94.74 %) (93.88%). Similarly, Rb/Sr are 0.74 1.22 Sr/Ba 0.89 0.69, respectively. These parameters portray them as supr...

The world-class Macraes orogenic gold deposit (∼10Moz resource) formed during the late metamorphic uplift of a metasedimentary schist belt in southern New Zealand. Mineralising fluids, metals and metalloids were derived from within the metasedimentary host. Helium and argon extracted from fluid inclusions in sulphide mineral grains (three crush extractions from one sample) have crustal signatur...

Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...

an important concern in rock mechanics is non-homogeneity as joints or fault. this noticeable feature of failures in rock is appearance of slip surfaces or shear bands, the characteristics of that are associated with deformation being concentrated in a narrow zones and the surrounding material remaining intact. adopting the joints as fractures, fractures are well known for their effects on the ...

introduction arefi quartz-bearing conglomerate (middle jurassic) is situated within binalud structural zone. the unit is trending nw-se located 25 km south of mashhad. more than 97% of the pebbles are quartz as mono-crystalline, poly-crystalline, and minor fragments of chert, quartzite, and mica schist. less that 3% of the remaining minerals are feldspar, mica, chlorite, hornblende, tourmaline,...

A variety of established and experimental geophysical techniques was used to measure the vertical distribution of fracture permeability in a 229-meter deep borehole penetrating schist and quartz monzonite near Mirror Lake, New Hampshire. The distribution of fractures in the borehole was determined by acoustic borehole televiewer and other geophysical logs. Fracture permeability was estimated by...
