Delineation 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...

Hydrothermal Alteration Zones Identification Based on Remote Sensing Data in the Mahin Area, West of Qazvin Province, Iran

The Mahin area is a part of TaromHashtjin zone that located in west of Qazvin province in northwest of Iran. Many copper and base metals ore deposits are hosted by this zone. High potential localities identification in this area is very necessary. The objective of this research, is finding hydrothermal alteration zones by remote sensing methods and best processing technique of Advanced Spacebor...

Survey on tick-borne pathogens in thoroughbred horses in the Hidaka district, Hokkaido, Japan.

A total of 87 Thoroughbred horses and 10 ixodid ticks from a ranch in Hidaka district, Hokkaido were tested for tick-borne diseases. Using the indirect fluorescent antibody (IFA) method, 3.4, 92.0 and 97.7% of the horses showed antibody titers of ≥ 80 against Anaplasma phagocytophilum, Rickettsia helvetica, and Borrelia garinii, respectively. This is the first report of infection with the 3 pat...

Further Investigations of a Conversion Series of Dioctahedral Mica/smectites in the Shinzan Hydrothermal Alteration Area, Northeast Japan

-A complete conversion series for mica/smectites was found in a hydrothermal alteration envelope around Kuroko-type ore deposits at the Shinzan area, Akita Prefecture, Northeast Japan. The minerals are an alteration product of volcanic glass of Miocene age and are commonly associated with zeolites and silica minerals. Degrees of ordering of interstratification of the minerals change discontinuo...
