RM1019   Hydrohetaerolite with calcite and hemimorphite

Precaución Mine, Cabezo de San Ginés, El Estrecho de San Ginés, Sierra Minera de Cartagena-L, Cartagena, Murcia, Spain

In the matrix of goethite we observe several cavities covered by small brilliant crystals, gray metallic luster; once analyzed results indicated to be hydrohetaerolite. We discuss whether it is hetaerolita, but analysis carried by Joan Viñals indicated the hydrated form. Under the SEM-EDS, tetragonal dipyramids are observed. It is accompanied by calcite crystals and hemimorphite (tabular crystals in book shape). SEM-EDS analysis will be sent to buyer.

Size: 7.3 x 6.4 x 6.3 cm.
