Epithermal Gold and Base Metal Mineralization at Gandy Deposit, North of Central Iran and the Role of Rhyolitic Intrusions
The Gandy gold-base metal deposit is located in Tertiary Torud-Chahshirin volcano-plutonic range, north of Central Iran. Various styles of gold mineralization occur throughout the range. Mineralization at Gandy occurs in close spatial relation with rhyolitic domes in a caldera setting in a series of narrow brecciated veins. Two mineralogically and spatially different argillic alterations have a...
متن کاملThe Bijvard epithermal gold-manganese prospect area, Northern Bardaskan, Khorasan Razavi: Evidence from geology, mineralization and geochemistry
Bijvard prospect area is located in the northern part of Central Iran zone, Sabzevar zone, about 40 km north of Bardaskan. The rock units exposed in the area include Cretaceous volcano-sedimentary rocks (andesite, basalt, graywacke and conglomerate) that syenogranite porphyry unit has intruded into them. Mineralization has structural control, with N35E trending, and has altered the andesitic r...

متن کاملSouth-Vergent Imbricate Fan in the Ikenodan Formation of the Shimanto Supergroup, Southern Kyushu, Japan
The Noda area in the Hokusatsu District, southwest Kyushu is underlain by the Imanokoba, the Ikenodan and the Ogakura Formations of the Cretaceous Shimanto Supergroup. The Imanokoba Formation comprises beds of sandstone and mudstone. The beds generally trend NE-SW and dip in a moderate to steep angles to the east or west. The Ikenodan Formation comprises beds of sandstone, mudstone, siliceous m...
متن کاملMiocene and Early Pliocene Epithermal Gold-Silver Deposits in the Northern Great Basin, Western United States: Characteristics, Distribution, and Relationship to Magmatism
Numerous important Miocene and early Pliocene epithermal Au-Ag deposits are present in the northern Great Basin. Most deposits are spatially and temporally related to two magmatic assemblages: bimodal basaltrhyolite and western andesite. These magmatic assemblages are petrogenetic suites that reflect variations in tectonic environment of magma generation. The bimodal assemblage is a K-rich thol...
