Lavra do Cruzeiro (Mina do Cruzeiro)
A gemstone and specimen mine in pegmatites.
Safira pegmatite district, Eastern Brazilian pegmatite province.
Note on the mineral list: for "coeruleolactite" see references and information given for Planerite-Turquoise Series.
Mine Information: This is one of the most important gem and specimen mines in the world. It was mined from about 1915, firstly for mica (muscovite), and was a major producer during WWII, after which mining efforts dropped dramatically. In the 1950s, mining resumed for tourmaline and other minerals.
Specimen mine accessed via a 4ft x 5ft adit that intercepts and follows the pegmatites via drifts, winzes, and at least one shaft for ventilation.
Development work utilizes drill+blast, but gem areas are excavated using hand-mining methods.
Regional Geology: In the southeast corner of the Macacos quadrangle a relatively large and arcuate mass of medium- to coarse-grained metagabbro is associated with talc schist and serpentinite in terrain of Rio das Velhas series rocks. The metagabbro consists of actinolite, hornblende, plagioclase (mostly albite), clinozoisite, and zoisite. Commonly the metagabbro is separated from the serpentinite by a zone of talc schist. Evidence found underground at the southwest end of the main level in the Cruzeiro asbestos mine indicates that the metagabbro has been partly altered, or replaced by talc near the contact with the serpentinite. In most places, this zone is sheared, resulting in talc schist, although the rock locally retains a gabbroic texture and appearance even when it is composed mostly of talc.
Mine Geology: There are at least five distinct pegmatites worked in the mine. They are hosted by Precambrian quartzites, mica schists, and amphibolites. The "amphibolites" are probably altered ultramafics, with olivine, pyroxene, and garnet (pyrope). Association minerals indicate the pegmatites are rich in lithium, boron, beryllium, manganese, tin, niobium, tantalum, phosphorus, uranium, and copper.
The pegmatites are classically zoned granite pegmatites and from the border to the core, the zones are typically
1. A thin mica-rich selvage
2. The main border zone of granitic rock
3. The outer intermediate zone with muscovite rich granite
4. The inner intermediate zone, mostly K-feldspar
5. The central zone, of most I interest mineralogically, with coarse-grained quartz and K-feldspar, and vugs with albite, tourmaline, and spodumene
6. A quartz core
Since the formation is weathered; with feldspars altered to kaolin, and spodumenes altered to montmorillonite; the tourmalines are typically recovered without matrix. Tourmaline indicators are cleavelandite, lepidolite, and coatings of iron-manganese oxides and phosphates.

ⓘ 'Planerite-Turquoise Series' Description: Originally reported to be coeruleolactite. All purported coeruleolactite examined by the authors of the 1998 report (Foord, E.E. & Taggart, J.E.) were largely Planerite, or Occasionally turquoise. Published analysis indicates that the vacany in the 'A' site is between 0.51-0.54 atom fraction, the balance in Cu-0.40 and Zn-0.06 to 0.09. It is suggested by this analysis that the turquoise structure likely cannot accomodate Ca in the 'A' site. |
