Description

Geoscience Fracture Set includes 6 number-coded specimens that each measure approximately 1-1/2 x 1-1/2 inches. Some minerals and rocks do not demonstrate a parting or cleavage along specific planes, but they do have a consistency in how they break. Set perfect for basic geology courses demonstrates important types of fractures like milky quartz conchoidal, kaolinite earthy, native copper hackly, galena smooth, serpentine splintery and hornblende uneven.
