Can green sand be found anywhere on Earth?

Yes, sort of. Green sand is actually olivine crystals, which has been eroded from lava rocks. Papakolea Beach (also known as Green Sand Beach, Mahana Beach and, erroneously, Puʻu Mahana) is a green sand beach located at South Point, in the Kaʻu district of the island of Hawaiʻi. One of only two green sand beaches in the United States, the other being in Guam, the beach gets distinctive coloring from olivine crystals found in a nearby cinder cone. Also, the famous green sand beach, Puu Mahana, near South Point in the Ka'u District is dominated by olivine, a common silicate mineral found in volcanic rocks, especially basalt lava. http://en.wikipedia.org/wiki/Olivine http://en.wikipedia.org/wiki/Papakolea_Beach http://www.westhawaiitoday.com/articles/2006/06/13/local/local02.prt Oct 12 09, 12:09 PM

I had the good fortune to live on the Big Island of Hawaii for more than ten years. Apart from the famous green sand beach small pockets olivine sand can be found along various beaches and seashores. There is a small subdivision near the town of Naalehu where there is enough of in the gravel used to grade the roads that the streets appear greenish in places. http://pixdaus.com/single.php?id=174007 Oct 12 09, 1:46 PM

Aside from finding green beaches, engineers commonly use green sand (found as sand or sandstone) for water treatment: " A green sand filter uses manganese green sand to filter iron, sulfur, hydrogen and manganese out of household and drinking water." http://www.ehow.com/how-does_4966040_green-sand-filter-work.html#ixzz1ktAne1yF See also http://en.wikipedia.org/wiki/Greensand Jan 29 12, 4:30 PM
