This study examines the sulfide mineralization of three of the ore zones within in the Lynne Zn-Cu-Pb deposit to determine how the mineralizing hydrothermal system formed and evolved over time. These sulfide mineral ores ...

The purpose of this project is to determine the specific style of hydrothermal alteration that occurs within the volcanic strata at Lynne Zn-Cu-Pb deposit. The Lynne deposit is a volcanogenic massive sulfide deposit (VMS) ...

The primary objective of this research was to describe the petrographic and geochemical characteristics of least-altered felsic volcaniclastic and coherent volcanic rocks that host Zn-Pb-Cu massive sulfides in the Lynne ...

This project is designed to examine the mineralogy, texture, and composition of the ore body and to determine the base and precious metal phases that are present in the primary ore zone.

Volcanogenic massive sulfide (VMS) deposits are polymetallic mineral deposits that contain many base and precious metals such as copper, zinc, lead, gold, and silver. This study focuses on two Paleoproterozoic VMS deposits ...

The Flambeau Cu-Zn deposit in northwestern Wisconsin, USA, is one of several volcanogenic massive sulfide (VMS) deposits in the state but remains the only one that has been mined because of unfavorable state mining ...

The Crandon massive sulfide deposit in Forest County, Wisconsin, is by far the largest polymetallic ore body in the Penokean Orogen. First discovered in 1976 by the Exxon Minerals Co., the company was eager to exploit the ...

The goal of this research project is to determine the petrogenesis of the stratigraphy hosting the Crandon Cu-Zn volcanogenic massive sulfide (VMS) deposit. Research material (core, documents, etc.), conducted by Exxon ...

The Lobo Zn-Cu deposit in northwestern WI, USA, is one of several volcanogenic massive sulfide (VMS) deposits in the state. This deposit has never been mined; therefore, further studies can only be conducted by examining ...

The rocks containing the Crandon deposit are part of the Pembine-Wausau Terrain and formed ~1.85 billion years ago. These formed in a bark-arc setting as part of the Penokean Orogeny. Arc-derived sediments eventually covered ...
