Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

sakhtehesar mountain is located in urumieh-dokhtar magmatic belt and is composed of volcanic and subvolcanic rocks (pliocene andesite to dacite) which intruded the volcanics and pyroclastics of paleocene age. three alteration zones including potassic, phyllic and propylitic are recognized in the area. in this paper, the mineral chemistry of magmatic and primary biotite and the mineral chemistry...

The Mexican subduction zone is a complex convergent margin characterized by slab with an unusual morphology, abnormal location of the volcanic arc, and existence slow earthquakes (slow slip events tectonic tremors). number seismic imaging studies has increased over past decade. These have revealed wave velocity structure beneath Central Southern Mexico. However, existing tomographic models are ...

Aim To (a) evaluate whether colonization of newly emerged high-elevation habitats occurred from neighbouring highlands (allopatric divergence and niche conservatism) or within the same mountain (peripatric parapatric shift) (b) test for effect past landscape configurations in geographically structuring biodiversity (a West–East structure spanning central part Transmexican Volcanic Belt). Locati...

The Stenopelmatus talpa species-group (Stenopelmatidae) comprises cricket-like orthopterans distributed across the Trans-Mexican Volcanic Belt (TMVB) morphotectonic province and adjacent areas in central Mexico. Despite recent efforts, taxonomy evolutionary relationships for members of this complex still are far from completely known. Here we generated characterized mitochondrial (mt) genome 14...

INTRODUCTION Regional metallogeny deals with broad aspects of the genesis of mineral deposits, particularly their distribution in time and space. Here we are concerned with such a study of a 28 700-square-kilometre area in the southwestern corner of British Columbia, including much of the Vancouver and Hope map-areas (NTS 92 G and H) and small parts of the adjoining mapareas to the north (NTS92...
