Winchite is also called Aluminowinchite or Eckrite.[3]
Chemistry
Winchite has a chemical composition similar to tremolite. But it contains iron, potassium, sodium, and manganese.[5]
Occurrence
Winchite occurs on grains of riebeckite.[6]: 137 It can be found in schist with metamorphosed manganese deposits.[7]
Distribution
It has been found on the south eastern part of Anglesey.[2] It has been found in Kajlidongri mine located in India as well at Ward creek in California.[7]
