The material on the gold content of coastal-marine deposits western coast Kamchatka is analyzed and resource potential briefly characterized. A review technological estimates obtained from study gold-bearing samples taken in promising areas strip, Bolshaya Vorovskaya River north to Cape Levashova south, presented. Stock materials supplemented by our studies were used. Gold-bearing with very fin...

Electron backscatter diffraction analysis of dendritic clinopyroxene (cpx) forming in rapidly cooled basalt reveals two features that are unexpected for phases growing from a liquid: (1) helical growth about {010}cpx, the crystallographic b-axis, with incremental rotation (up to 0.4° μm–1) within branch segments and large rotational jumps (10°–46°) between closely spaced branch segments, and (2...

introduction the fanuj titaniferous placer deposits are located 35 km northwest of the fanuj, sistan and baluchestan province (1) . the studied area comprises a (2) small part of the late cretaceous fanuj-maskutan (rameshk) ophiolite complex (arshadi and mahdavi, 1987). reconnaissance and comprehensive exploration programs in the fanuj district (east of the 1:100000 fanuj quadrangle map,yazdi, ...

The ca. 1.83 Ga Trans-Hudson orogeny resulted from collision of an upper plate consisting the Hearne, Rae, and Slave provinces with a lower Superior province. While geologic record peak metamorphism within orogen suggests that these were single amalgamated craton this time onward, lack paleomagnetic poles province following orogenesis has made coherency difficult to test. We develop high-qualit...

A new influx of sea-rafted pumice reached the eastern coast of Australia in October 2002, approximately 1 year after a felsic, shallow-marine explosive eruption at a previously unknown volcano (0403-091) along the Tofua volcanic arc (Tonga). The eruption produced floating pumice rafts that first became stranded in Fiji in November 2001, approximately 1 month after the eruption. Strandings of se...

High-resolution records of the upper Olduvai geomagnetic field reversal were obtained from two localities within steeply dipping lacustrine sediments of the Confidence Hills, southern Death Valley, California . The difference in bedding attitude between the two localities allowed us to perform a fold test of both transitional and non-transitional paleomagnetic directions. This is the first posi...
