The Empire State mine in Balmat, New York, is known for its fine mineral specimens, including sphalerites, calcites, pyrite, pyrrhotite, halite, and quartz. The article acknowledges the lack of detailed documentation on mineral discoveries in the area but provides a list of 116 known minerals from the Balmat mines. The Empire State mine, owned by Titan Mining Corporation, is one of six zinc mines in the region. The rocks in the mines have undergone metamorphism, and the formation of mineral pockets occurred due to fluid movements. Recent discoveries of minerals in the mine have attracted attention from collectors and researchers, and it is hoped that future documentation will provide more information about these finds.

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.

It is found on some of the tourmaline crystals in low- to high-luster, hexagonal, white and yellowish-green crystals to 3 cm, though most are less than 1 cm. The white color of some crystals may be due to weathering. The Dafoe home sits directly on, and adjacent to, several tourmaline-bearing dikes (Chamberlain et al. [4]) containing an abundance of fine minerals similar to, yet different in some respects from, those found at the Powers farm. All photos by Michael R. Walter of specimens from the Dafoe property, Pierrepont, St. Lawrence County, New York In 2019 we wrote a short preliminary article on the minerals being recovered at the Dafoe property in the township of Pierrepont, St. Lawrence County, New York (Walter and Robinson [7]). What is most striking is the overwhelming influence of hematite on all the dikes found on the Dafoe property and the total lack of this mineral in the Powers farm dikes, and, for that matter, in all the other Powers tourmaline occurrences.

Reproduced with permission B Hamilton hill b in Russell is a locality known for huge tremolite crystals but even more so for being the locality where the largest tourmaline (dravite) ever found in St. Lawrence County was recovered (Chamberlain [1]). The Hall farm is well known for fine tremolite crystals in a region that has many tremolite occurrences. Tremolite crystals found here are colorless to gray, lustrous, and often form epitactic overgrowths on diopside with alteration to talc, creating pseudomorphs after diopside. All specimen photographs by Michael R. Walter Tremolite, Ca SB 2 sb Mg SB 5 sb Si SB 8 sb O SB 22 sb (OH) SB 2 sb , is an important rock-forming mineral. [Extracted from the article]

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.

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 road-cut mineral occurrences of St. Lawrence County, New York which involves minerals like Dravite crystal, Calcite and quartz. It mentions that basement rocks of St. Lawrence County, New York are metamorphosed sediments (meta-sediments) of Precambrian age. It states that sampling of mineralization in St. Lawrence County, New York, represented by road cuts depends on density of roads and frequency with which they are improved by being straightened or widened.

The article reports that Lead Mine Road gash veins can be found on the southern shoulder of Lead Mine Road in the town of Macomb, approximately 200 yards from the border between the towns of Macomb and Gouverneur, St. Lawrence County, New York. The small hill containing the Lead Mine Road gash veins is composed of Grenville-aged marble. The marble comprising most of the hill is a fine-grained, impure marble that contains abundant grains and flakes of graphite.

The article presents the mineral occurrences located at the road-cut of St. Lawrence County in New York. Topics discussed, include the discover of crystallized barite that produces hundreds of desirable specimens in 2013, the discovery of a large quantity of crystallized barite by mineral collector Donald M. Carlin in a road cut and the difference of physical mode of occurrence of mineralized fractures from other localities.

The article focuses on the mineral occurrence in the Precambrian rocks of St. Lawrence County, New York particularly prehnite. It says that the mineralization has been exposed due to road improvements and occurs in a low-temperature, hydrothermal quartz-feldspar vein. It mentions that scanning electron microscope energy dispersive analyses has been integrated to identify chabazite crystals like Chalcopyrite (CuFeS2), Calcite (CaCO3), and Fluorite (CaF2).

The article discusses the mineral occurrences found by the authors at the Yellow Lake South (YLS) and the Yellow Lake North (NLS) in the town of Macomb, St. Lawrence County in New York.

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.
