Geology of the Archean Côté Gold Au(-Cu) intrusion-related deposit, Swayze Greenstone Belt, Ontario
… multi-phase tonalite, diorite and quartz diorite intrusions of the Chester intrusive complex (CIC), a multi-phased, laccolith-shaped synvolcanic intrusion. Crosscutting relationships suggest coeval emplacement of the host rocks and high-precision UPb ID-TIMS zircon geochronology results constrain …

Paragenetic Evolution of the Robertson Deposit: Eocene Intrusion Related Gold Deposit in the Northern Shoshone Range, Nevada
… deposit, formerly known as Tenabo, is an Eocene intrusion-related gold deposit 5 km north of Pipeline, which is a 20 Moz+ Carlin-type gold deposit in the northern Shoshone Range, Nevada. Carlin-type gold deposits have been the focus of many studies as they represent the second largest …

Time-Space Relationships between Sediment-Hosted Gold Mineralization and Intrusion-Related Polymetallic Mineralization at Kinsley Mountain, NV
… spatially associated with upper crustal felsic intrusions, epithermal deposits hosted by carbonate rocks, and epizonal orogenic deposits hosted by carbonate rocks. A very important question to resolve is whether CTGDs and SHGDs represent a spectrum of deposits with a shared origin, in which …

Buffalo Canyon: An Oligocene Greisen-Like Intrusion-Related Gold Deposit in the Union Mining District, Nye County, Nevada
Reduced intrusion-related gold (RIRG) deposits have been documented around the globe, and have been best studied in Alaska and Yukon, but few examples have been documented in Nevada. One occurrence in Nevada is the Jurassic Bald Mountain deposit in eastern Nevada; however, for most Nevada …

Gold mineralization in the Missanabie-Renabie district of the Wawa subprovince (Missanabie, Ontario, Canada)
… Ontario, Canada) have been interpreted as both intrusion-related and metamorphic-hydrothermal in origin. The veins were mined at the past-producing Renabie mine, which yielded ~1.1 Moz of gold during production from 1941-1991. Whereas the intrusion-related interpretation links the veins to …

Gold and Base Metal Mineralization, Hydrothermal Alteration and Vein Paragenesis in the Spring Valley Deposit, Pershing County, Nevada
… disproved, and alternate orogenic and reduced intrusion-related gold interpretations are presented. Vein-related alteration is relatively consistent throughout the Quartz-eye Rhyolite, Welded Tuff, Agglomerate and Feldspar Porphyry members of the Rochester Formation, though it is better …

Intrusive cognitions, anxiety and cancer
… have rarely explored the content or nature of intrusions. In addition to verbal intrusions, intrusive memories of illness have been reported in cancer patients. More recently, intrusive imagery has been found in populations of anxious patients and reported to have a causal role in the …

Patterns of distal alteration zonation around Antamina Cu-Zn skarn and Uchucchacua Ag-base metal vein deposits, Peru : mineralogical, chemical and isotopic evidence for fluid composition, and infiltration, and implications for mineral exploration
Intrusion-related, carbonate rock–hosted replacement deposits are an important source of global base metal production that includes: Cu-Zn skarn, Zn-Pb-Ag carbonate replacement and Ag-base metal deposits. These deposits are located in multiple geological settings and are commonly associated with …

A Comparison of Geochemistry, Carbonate Mineralogy, and Argillic Alteration between the Dome Prospect and the Main Au Resource of the Donlin Creek Project in Southwest Alaska
… base-metal assemblage fall into the high-level intrusion-related ore deposit-type that is characteristic of the Kuskokwim Mineral Belt.

Neural Processes Underlying the Intrusion of Unwanted Memories
… the attentional processes underlying the sudden intrusion of unwanted memories into our awareness is of great importance. This thesis investigates the attentional mechanisms involved in the intrusion of unwanted memories using functional magnetic resonance imaging (fMRI) and the Think/No-Think …
