The wollastonite and resulting pseudomorphs are fairly sharply crystallized and occur either as isolated crystals in areas of coarsely crystallized calcite or as crystals lining the walls of a diopside-albite rock that faces into coarsely crystallized calcite. PSEUDOMORPHS Wollastonite Skarn (WSK) Almost all the pseudomorphs observed at the WSK are alterations or replacements of primary wollastonite. A detailed preliminary study concluded that the original mineral was unlikely to be nepheline but could have been cordierite, based on the presence of crystallized quartz in the mineral assemblage of the occurrence and the likelihood from contact goniometry that the original mineral was orthorhombic rather than hexagonal. The following observations support our conclusion that these pseudomorphs resulted from later alteration of preexisting meionite crystals: We have observed no marialite crystals without a meionite core.

Were it possible to remove the marialite, the surface texture of the underlying meionite would be markedly irregular; however, the surface texture of those meionite crystals without an external layer of marialite is smooth and glassy. All the scapolite crystals we have examined have internal meionite, i.e., there are no crystals made up solely of marialite. Most commonly, meionite crystals have an external rind of opaque pale tan to white marialite, but some crystals are lustrous gray prisms with no marialite overgrowth. The Purple Diopside Mound is almost newly discovered (2012) compared to the adjacent Wollastonite Skarn, which has been a productive locality for mineral collectors for nearly 140 years.

Other metasedimentary rocks nearby include biotite-quartz-plagioclase gneisses (bqp) of the Popple Hill Gneiss ([5]) to the west of the marble belt and a unit of calc-silicate gneisses (cs) known as the Irish Hill Gneiss ([19]) to the east. Zircon is generally not common in marble, and its discovery in the skarnlike assemblages at Rose Road tells us that the rocks investigated have a history that allowed for the deposition and/or growth of zircon. U-Th-Pb zircon results for zircon separated from the Wollastonite Skarn at Rose Road. U-Th-Pb zircon results for zircon and titanite separated from the Farr property near Natural Bridge: (A) Zircon analyses interpreted as representing the timing of the formation of the Farr property skarn.

The article focuses on the Powers farm black tourmaline locality at Pierrepont, which is one of the best-known mineral collecting sites in northern New York State. Topics include it has been known for decades that interesting minerals also occur on the adjacent property across Leonard Brook and the principal locality consists of a single tourmaline bearing pegmatite vein on a small rise near the Dafoe residence.

The article offers information on the mineral collection from Pitcairn in St. Lawrence County, New York. Topics discussed include collection of clove-brown titanite, tan wollastonite, bright blue fluorapatite; albite and diopside collected by George Huntington Williams; and discovery of the wollastonite skarn.

The article discusses the discovery of danburite crystals in the town of Macomb in Saint Lawrence County, New York. Information regarding the history of the discovery by Andy and Scott Sutherland in 2014, the occurrence of danburite crystals between an albite-quartz pegmatite and marble, and the chemical composition of pegmatite and albite, are discussed.

The article focuses on brown tourmaline locale found on the Bush farm, St. Lawrence County, Gouverneur, U.S. that is a rich source of quality fluoruvite. It is suggested that that for the past 150 years, many collectors have been paying a visit to it. Details related to its location and its geology are presented. The description of the minerals is also presented.

The article focuses on the tremolite and tourmaline mineral along the Selleck Road locality close to the village of West Pierrepont town in Saint Lawrence County, New York. Topics discussed include the history of several occurences of crystallized tremolite east of the town, the rocks exposed at the locality consist an assemblage of crystalline Precambrian rocks, and various specimens recovered in 2011 including holmes rock, walter-crump pit, and tremolite pits.

The article focuses on the discovery of magnetite crystals by Zinc Corp. of America, a mining company, at the Fowler orebody in Saint Lawrence County, New York. The crystals occurred either lining halite-field veins, along with anhydrite, calcite, and sphalerite in a matrix of halite and talc. The history of zinc mining in the state is also discussed.

The article profiles three historic mineral collectors in New York. Oren Root's contributions to geology are undocumented, except for his role in the discovery of the kiberlite dike in Syracuse. Elmer B. Rowley assembled a fine collection of minerals and made several mineral specimen discoveries in the Adirodack Mountain region. David Edward Jensen assembled an important collection of minerals that is displayed at the Buffalo Museum of Science.

The article presents information on several collectors' gems of New York State. They include garnet, which was designated as New York's official state gemstone in 1969 and is a common accessory mineral in many of the crystalline rocks in the state. Another is the feldspar group, which includes a potassium-rich subgroup of species. Titanite is probably the finest gem-quality ever found in North America in 1891.

The article reports on the major mineral localities of New York State. The sources of information on minerals of interest to collectors in the state include Samuel Robinsons' "A Catalogue of American Minerals With Their Localities" in 1825 and "Minerals of New York State," by David Jensen. The major mineral localities include Albany County, Bronx County, and Clinton County.

The article offers information on the Huron River uranium prospect, a base- and precious-metal exploration in the vicinity of the Huron River drainage system and the western flanks of the adjacent Huron Mountains in northern Baraga County, Michigan. It discusses the history of mineral exploration along Huron River. The exploration had identified one mineraloid, and three unknown minerals.
