Transmission electron microscopy of muscovite alteration of tourmaline
Partially sericitized tourmaline from a pegmatite was investigated using high-resolution transmission electron microscopy (HRTEM). Fine-grained muscovite crystals form extensive narrow veinlets preferentially developed along the {110} and {100} cleavages of tourmaline, indicating that a cleavage-controlled alteration mechanism was dominant. HRTEM images show that tourmaline-muscovite interfaces...
متن کاملDelineation of hydrothermal alteration Zones for porphyry systems utilizing ASTER data in Jebal barez area, SE Iran
Abstract: The Urumieh-Dokhtar Magmatic Belt (UDMB) is the host of many Iranian Cu porphyry deposits. Southern part of this belt, in the range of geological Jebal barez, has been less investigated because of the mountainous and rough topography and also some security confrontation. Porphyry deposits are associated with hydrothermal alteration zones can be mapped using remote sensing data such as...
متن کاملHydrothermal alteration mapping using ASTER data in Baogutu porphyry deposit, China
Remote sensing plays an important role in mineral exploration. One of its proven applications is extracting host-rock lithology and alteration zones that are related to porphyry copper deposits. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to map the Baogutu porphyry deposit alteration area. A circular alteration mineral zoning pattern was clearly observed ...
متن کاملApplication of fractal modeling to delineate alteration zones and lithological units in Masjed-Daghi Cu-Au porphyry deposit, NW Iran
In this paper, we aim to present a quantitative modeling for delineating the alteration zones and lithological units in the hypogene zone of Masjed-Daghi Cu-Au porphyry deposit (NW Iran) based on the drill core data. The main goal of this work is to apply Ordinary Kriging (OK) and concentration-volume (C-V) fractal model based on Cu grades in order to separate the different alteration zones and...
متن کاملGeology and Alteration at the Mount Milligan Gold-copper Porphyry Deposit, Central British Columbia
The Mount Milligan deposit, centred at latitude SS”O8’ north and longitude 124”04’ west, is 100 kilometres westsouthwest of Mackenzie and 160 kilometres northwest of Prince George in central British Columbia. The deposit occurs in gently rolling topography (Plate 2-6-l) 5 kilometres due south of Mount Milligan. Access to the property is by a 93.kilometre logging road that connects with the Hart...
