Chlorite & Quartz Crystals

  The term “Chlorite” refers to a group of clay minerals that form at cooler temperatures than quartz and often enter the crystal pocket in the latter phases of quartz formation. Chlorite is often a soft greenish color but it can occur in a variety of colors: grey, tan, reddish, white or brown.
  Chlorite that enters the quartz pocket at an early phase of crystal formation often settles to the bottom of the cavern as it is heavier than the watery, liquid matrix in which the quartz forms.  Clear quartz crystals may subsequently grown through or around the chlorite, often enclosing the chlorite at the bottom of the crystal.  At times we also find chlorite as a part of the crystal matrix or adhered to the exterior of the crystals.
  Chlorite-included crystals are often found in Alpine-type environments such as the Himalayan mountains.  Alpine-type "clefts" or fissures are rare geological occurrences in which chlorite is often one of the minerals found in abundance.
