The towering peaks and plateaus of the Cordillera took shape millions of years ago, when the westward moving North American tectonic plate collided with the Pacific plate. The collision uplifted mountain chains in British Columbia and the Yukon.

Ray; L. Carlyle; R. Simpson; L. Saleken; J. Bellamy; J. Shearer; R. Niels. Compared to epithermal deposits, mesothermal deposits have higher As, W, and Au/Ag values, higher CO 2 content in fluid inclusions, and δ 18 O values of ore-forming fluids of +3‰ to +10‰ vs.

−14‰ to −7‰ for epithermal deposits. Like the gold deposits in Nevada and Colorado, epithermal mineralization in the Canadian Cordillera Cited by: A "cordillera" is a chain of mountains, and there are many different chains of mountains in Canada's Cordillera region.

In between the mountains there are fertile valleys, lakes and rolling hills. ON the coast, there are deep harbours, sheltered waterways, and deltas. The region also includes very old forests, rivers, deserts, and beaches. Gold deposits are found in a great variety of rocks; but, as might be expected from the close connection with igneous intrusions, the most favorable rocks are of the metamorphic kind, particularly mica schist, quartzite, and slate.

Limestone is not as favorable; but some of. The Los Bronces and adjacent Rio Blanco mines exploit a single porphyry Cu deposit which is located on the western side of the Andes in Central Chile, some 69 km west of Santiago. Like the El Teniente deposit a km to the south, it was formed in the early Miocene to Pliocene, and is one of the largest of the ore deposits of this age grouping.

H istorically, gold has been considered unimportant in sedimentary exhalative (sedex) Zn-Pb and barite r, recent work in Nevada has demonstrated that the host rocks of mid-Tertiary Carlin-type gold deposits also contain Devonian sedex mineralization, which is significant because these deposits will be mined for gold and not Zn-Pb or barite (Emsbo et al.,).

Mining Exploration Process. On the North American continent, the westernmost physiographic region that extends from Mexico to Alaska is commonly called the Western Cordillera, Cordilleran region, or simply Cordillera. The Canadian portion of this system includes the Rocky Mountains and the Coast Mountains.

Fifty-six principal gold deposits in the western Pacific region were generated in multiple volcanoplutonic arcs during the last 25 million years. At least 75% of the contained gold was introduced in association with intrusive stocks, commonly by: 1.
