A review of case histories of reservoir-induced seismicity (RIS) in China shows that it mainly occurs in granitic and karst terranes. Seismicity in granitic terranes is mainly associated with pore pressure diffusion whereas in karst terranes the chemical effect of water appears to play a major role in triggering RIS. In view of the characteristic features of RIS in China, we can expect moderate...

A provenance study was conducted on the Mid-Proterozoic Newland Formation, in which petrographical features of sandstones and geochemical characteristics of shales were integrated to arrive at an internally consistent interpretation. Sandstones of the Newland Formation are typically arkosic sands and arkoses with very well rounded quartz and feldspar grains and only minor amounts of extrabasina...

Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...

The fate of organic herbicides applied to agricultural fields may be affected by other soil amendments, such as copper applied as a fungicide. The effect of copper on the leaching of diuron and glyphosate through a granitic and a calcareous soil was studied in the laboratory using sieved-soil columns. Each soil was enriched with copper sulfate to obtain soil copper concentrations of 125, 250, 5...

This paper describes a methodology for the documentation and analysis of historical buildings. Techniques of digital image processing give the possibility to detect damages, such as moisture or biological changes, on surfaces of monuments. Intensity data obtained from laser scanner equipment and colour information gathered with a digital camera were evaluated for damage identification that affe...

The charnockitic and associated granitic rocks of Akure area were studied for their field and petrographic relationship's. The outcrops locations were plotted in Surfer 8. The granitic rock exhibits a porphyritic texture and outcrops in the north-eastern side of the study area while the charnockitics outcrop in the central/western part. An essentially dark coloured and fine grained intrusive ex...

(Floristic and vegetation structure of a granitic grassland in Southern Brazil). A floristic and structural survey of a natural grassland community was conducted on Morro do Osso, a granitic hill in Porto Alegre, RS, Brazil. Structural data were surveyed in 39 one square meter plots placed over two major grassland areas. An accidental fire has occurred in one of the areas approximately one year...

At the Kakkonb geothermal area, Japan, a large Quaternary granitic body is dstributed below ca 2.5 km ckpth from the surface, associating with thick high-temperature contact me&amorphic zones in the overlying formations, and a meteoric-water-cbminated type hydrothermal system is developedat present time. During the 'Deep-seated Geothermal Resources Survey', WD-la well was drilled to 3729 m dept...

Access to a granitic rock mass in an iron ore mine in Sweden provided a unique opportunity for underground experiments related to the geologic disposal of radioactive waste. These field tests demonstrated the importance of hydrogeology and the difficulties in predicting the thermomechanical behavior of fractured granitic rocks. To characterize a site fully, measurements made from the surface mu...
