Calcite crystals on matte brown matrix Pseudomorph and covers the surface enoughLocale: Santa Eulalia, Chihuahua, Mexico Approx dimensions: 4. 5 x 2. 25 x . 75" Approx weight: 107g This specimen from Santa Eulalia has modified rhombohedral calcite crystals on a brown iron oxide matrix. Ripples and flow patterns indicate water was involved in the deposition of the brown sandy textured layered crust, which appears matte but glitters under direct light. The large calcite crystals are heavily included with hematite (iron oxides) and
