Pale green mica-rich rock (possibly chlorite schist)
Likely chlorite schist; identification is uncertain from the photograph
AI-generated identification · may be incorrectPale green to gray, with a fine-to-medium-grained, flaky or foliated appearance and a weak sheen. If chlorite-rich, hardness is about 2–2.5 Mohs; the specimen is too small and indistinct to confirm its minerals or cleavage visually.

Physical properties
Pale green to gray, with a fine-to-medium-grained, flaky or foliated appearance and a weak sheen. If chlorite-rich, hardness is about 2–2.5 Mohs; the specimen is too small and indistinct to confirm its minerals or cleavage visually.
Formation & geological history
Chlorite schist forms when pre-existing rocks are metamorphosed under low- to medium-grade conditions; its age and source cannot be determined from the image.
Uses & applications
Schist is used as decorative or landscaping stone and collected as a geological specimen; this small piece has no evident commercial use.
Geological facts
Green color in metamorphic rocks can come from chlorite, though other minerals may look similar.
Field identification & locations
Check for aligned, shiny mineral flakes and splitting along layers; a fresh surface and mineral tests would help distinguish chlorite schist from other green rocks. Schists occur in metamorphic belts worldwide.
