Wood's Mine


A former Cr mine located near Texas, approximately 6 miles (ca. 10 km) N of Rising Sun, MD, USA. Note: Texas is rarely designated on most regional maps.

Mineralization is a Cr deposit hosted in serpentine.

NOTE: As of Summer 2012, the property/mine is closed to collectors.

Concerning zaratite:
In an investigation of the status of zaratite, a single study sample from Woods Mine (Texas) of zaratite was analyzed by multiple methods and found to be near gaspΓ©ite. The authors' data suggest that the natural nickel hydroxycarbonate materials from the three various locality samples employed, including its type locality, collectively referred to as β€˜zaratite’ on the basis of colour, occurrence and poor crystallinity, are in fact so diverse in terms of Ni/C/H ratios that the β€˜zaratite’ term should not deserve a species status and so remains highly questionable.*

*Ref: Garcia-Guinea, J., La Iglesia, A., Crespo-Feo, E., GonzΓ‘lez del Tanago, J., Correcher, V. (2014) The status of zaratite; investigation of the type specimen from Cape Ortegal, Galicia, Spain. European Journal of Mineralogy: 25: 995-1004.

Detailed Mineral List:

β“˜ Antigorite
Formula: Mg3(Si2O5)(OH)4
Habit: thin lamellar, laminae easily separable into translucent folia
Colour: leek green to violet in "chromium" variety
Description: Antigorite occurs both with typical leek green coloration and the violet coloration of so named "Chromium" Antigorite. Specimens of Chromium Antigorite were often reffered to as Kammererite, or Chromium Clinoclore, but this is inaccurate. (see www.pennminerals.com/museum.htm for a good image of an actual, and very rare, Kammererite from Woods Chrome). Specimens of Chromium Antigorite from this occurance even fall somewhat short of a true Antigorite identity, but is closest to this family member of the Sepentine group.
β“˜ Antigorite var. Williamsite
Formula: Mg3(Si2O5)(OH)4
Habit: micro-fiberous
Colour: Apple green to Emerald green
Description: A beautiful Apple Green variety, Williamsite, first described at Woods Chrome in 1849 by Lewis W. Williams, whom also first described Zaratite (Emerald Nickel) the same year. Williamsite is a semi-precious variety of Sepentine, usually in association with chromite.
β“˜ Aragonite
Formula: CaCO3
βœͺ Brucite
Formula: Mg(OH)2
Habit: tabular plates with pseudo-hexagonal edging. usually foliaed masses
Colour: white to pale green, pearly to waxy luster, transparent in thin sections/plates
Fluorescence: bright blue-white response
Description: Worlds finest locality for the Brucite, hosting the largest crystal ever found (to 0.2m). Crystals from here are rich and well developed, in numerous modifications including large tabular crystals and occasional groups in rosettes. coloration from this locale tends towards pale green coloration in the richest specimens.
β“˜ Cacoxenite
Formula: Fe3+24AlO6(PO4)17(OH)12 · 75H2O
β“˜ Calcite
Formula: CaCO3
References:
Dana 6:1069.
β“˜ Chromite
Formula: Fe2+Cr3+2O4
Habit: massive, fine grained. frequent admixture with Serpentine
Colour: Blackish grey
Fluorescence: none
Description: Chromite, the Major ore at Wood's Mine. By 1874 report, Chromite production in PA was already waining, however the production to date at Wood's Mine of 120,000 tons, exceeded 20 times the production of all other PA chomite mining localities combined.

Formula: Mg3(Si2O5)(OH)4
β“˜ Clinochlore
Formula: Mg5Al(AlSi3O10)(OH)8

Formula: D3[Si2O5](OH)4
Habit: crystaline Massive
Colour: brilliant green
Fluorescence: none
Description: Type locality for variety "Williamsite", a gemmy bright green serpentine often used as a semi-precious stone. Often associated with Chromite at this locality. discovered in 1849 by Lewis W. Williams, whom also first described Zaratite (Emerald Nickel) at Wood's Chrome Mine the same year.

Habit: crystaline massive veins and coatings typical, admixture with Dolomite
Colour: Brilliant Green
Fluorescence: none
Description: Lewis W. Williams first described Zaratite, as "Emerald Nickel" at Wood's Chrome Mine in 1849, nearly making Wood's Chome Mine "Type Locale" for the species. (TL: Spain 1851) Frequently occuring in admixture with micro crystals of dolomite, referred to localy as "pennite".
