Viet Nam is currently home to UNESCO-recognized Dong Van Karst Plateau Geopark in the northernmost province of Ha Giang and Non Nuoc Cao Bang Geopark in the northern province of Cao Bang.
Head of Quang Ngai Province’s culture, sports and tourism Nguyen Minh Tri said that since January 2018, 11 mineral geological surveys, landscape geomorphologies, cultural geographies have been carried out at nine districts in the province with the participation of top domestic and foreign professionals.
The geopark will include 7,925ha of the Ly Son Marine Conservation site, 1,000ha of Ca Dam Nature Reserve and another 39,000ha of reserve in the west of Ba To district.
According to scientists, magma sample research and field examination showed the volcano erupted to create Quang Ngai sometime between 6.9 million and 9 million years ago.
Ly Son island witnessed at least three periods of volcanism with eruption areas from Ly Son to Phu Yen province and Phu Quy Island in Binh Thuan province.
Samples of metamorphic and igneous rocks found in QuangNgai are believed to have been formed from 250 million to 460 million years ago.
At least three complexes of metamorphic and igneous rock and 12 magma complexes helped create some areas in Quang Ngai (Ba To and Tra Bong districts).
