moraine

Anhua is located at 111°13' east longitude and 28°23' north latitude. The area is 82% mountainous, with an average annual temperature of 16.2℃-17.6℃, 275 frost-free days, and 1335.8 hours of sunshine. The full name of moraine is moraine gravel mudstone, which is one of the rare stone species in the world. It is gray-brown, dark brown, heavy, hard and brittle, and contains sandstone or other small biological fossils.

According to research, moraine was formed about 600-700 million years ago. At that time, the "ice ball event" of the global "ice sheet climate" occurred on the earth, and after the ice age, the "hot chamber climate" event occurred. This phenomenon of extreme heat and extreme cold formed the rare moraine.
The moraine area is particularly rich in trace elements such as zinc and selenium that are urgently needed by the human body.
