Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits
Records of the Australian Museum (2001) Vol. 53: 49–56. ISSN 0067-1975 Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits MARTIN J. CRANE, JAMES L. SHARPE AND PETER A. WILLIAMS School of Science, University of Western Sydney, Locked Bag 1797, Penrith South DC NSW 1797, Australia [email protected] (corresponding author) ABSTRACT. Intense weathering of copper orebodies in New South Wales and Queensland, Australia has produced an unusual suite of secondary copper minerals comprising chrysocolla, azurite, malachite and the phosphates libethenite and pseudomalachite. The phosphates persist in outcrop and show a marked zoning with libethenite confined to near-surface areas. Abundant chrysocolla is also found in these environments, but never replaces the two secondary phosphates or azurite. This leads to unusual assemblages of secondary copper minerals, that can, however, be explained by equilibrium models. Data from the literature are used to develop a comprehensive geochemical model that describes for the first time the origin and geochemical setting of this style of economically important mineralization.

Abstract The early Silurian reefs of the Attawapiskat Formation in the Hudson Bay Basin preserved the oldest record of major invasion of the coral-stromatoporoid skeletal reefs by brachiopods and other marine shelly benthos, providing an excellent opportunity for studying the early evolution, functional morphology, and community organization of the rich and diverse reef-dwelling brachiopods. Biometric and multivariate analysis demonstrate that the reef-dwelling Pentameroides septentrionalis evolved from the level- bottom-dwelling Pentameroides subrectus to develop a larger and more globular shell. -

Deposits of Manganese Ore in Arizona
DEPOSITS OF MANGANESE ORE IN ARIZONA. By E. L. JONES, Jr., and F. L. RANSOME. INTRODUCTION. By E. L. JONES, Jr. FIELD WORK. Deposits of manganese ore have long been known in some of the old mining districts of Arizona, notably in the Bisbee, Tombstone, Globe, and Patagonia districts, but prior to 1915 the ore had not been mined except as it formed the gangue of silver ores and was needed as a flux for use in local smelters. Manganese ore as such was first shipped from the Tombstone district in 1915, and from the Globe and Bisbee districts in 1916. The high prices that were offered, for manganese ore in 1916, 1917, and 1918, and the fact that the opening of the new deposits would render the Government patriotic service greatly stimulated the production of the ore and the search' for new deposits. As a result of this search discoveries in many parts of the State have been reported to Government bureaus from time to time. In order to obtain information concerning these newly discovered deposits, their character and grade of ore, ore reserves, and pro ductive capacity, two geologists of the United States Geological Survey examined manganese deposits in Arizona, E. L. Jones, jr., visiting many scattered deposits throughout the State, > and F. L. Ransome those of the Bisbee and Tombstone districts. The work of Mr. Jones was done in August and September, 1917, and in April, May, and June, 1918. It was geologic reconnaissance work, and generally not more than a few hours could be devoted to the examination of each deposit. -

Simon, Chief COVER PHOTO: Faulted and shattered Silurian dolomite in the Meyer Material Company quarry (Vick's Pit) located within the Sandwich Fault Zone about six miles southwest of Joliet, Will County, Illinois. A major fault with approximately 100 feet of displacement is marked by the white line. Rocks of the Wilhelmi Formation on the left are upthrown in juxtaposition with the Joliet Formation on the right. Numerous, small high-angle faults and joints can be seen in the highwall. The faulted Silurian dolomite is truncated to a flat surface and is covered by approximately 20 feet of the Wisconsinan Yorkville Till Member. Kolata, Dennis R.
