In SW Piemonte the Western Alps arc ends off in a narrow, E-W trending zone, where some geological domains of converged. Based on critical review available data, integrated with new field it is concluded that southern termination recorded Oligocene-Miocene activity regional transfer zone (southwestern Transfer, SWAT) already postulated literature, which should have allowed, since early Oligocen...

The core of detrital zircons from the southern Meiganga gold-bearing placers were analyzed by Laser Ablation Split Stream analytical techniques to determine their trace element abundances and U-Pb ages. obtained data used characterize each grain, its formation condition, try provenance. Hf (5980 12,010 ppm), Y (27–1650 U (25–954 Th (8–674 Ti (2–256 Ta, Nb, Sr (mainly <5 Th/U (0.06–2.35), zir...

The Grand Forks complex, northern equivalent to the Kettle dome in the United States (e,g, Cheney, 1977; Cheney, 1980; Rhodes and Cheney, 1981), is one of many exposures of high-grade metamorphic rocks of North American miogeoclinal affinity in the southern Omineca Belt (Figure 1). These structural culminations bounded by Tertiary normal faults, often collectively referred to as the Shuswap com...

Although testing is the mostpopular method for assuring sofrware quality, there are two recognized limitations, known as the reliable test set problem and the oracle problem. Fault-based testing is un attempt by Morell to alleviate the reliable test set problem. In this papec we propose to enhance fault-based testing to address the oracle problem as well. We present an integrated method that co...

The studied area, as Ykeh-Chah unit, is a part of Golpayegan magmatic and metamorphic complex in Sanandaj-Sirjan structural zone. The unit consists of mylonitized and high- grade metamorphic rocks, including biotite-gneiss, biotite-garnet-gneiss, amphibolite and orthogneiss. The biotite gneiss and the biotite garnet gneiss have partly been migmatitized. They show various structures such as stro...
