2021年4月21日 · Large-scale lava experiments are helping scientists imagine how metallic lava would flow across and shape a landscape, either on Earth or on a distant asteroid. Researchers explored what...

Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks .

Since 2009, the Syracuse Lava Project has been recreating lava flows under controlled conditions on the Syracuse University campus by melting rocks to different temperatures using furnaces. They create meter-scale flows of molten basaltic lava, the same black lava that covers the seafloor, Hawaii, Iceland and other volcanic terranes on Earth ...

Aluminum ore, called bauxite, is most commonly formed in deeply weathered rocks. In some locations, deeply weather volcanic rocks, usually basalt, form bauxite deposits. This sample of bauxite ore is from Western Australia. Aluminum has a wide range of common uses. It is lightweight, strong (especially with alloys), and conducts heat well.

What would a volcano -- and its lava flows -- look like on a planetary body made primarily of metal? A pilot study from North Carolina State University offers insights into ferrovolcanism that could help scientists interpret landscape features on other worlds.

2017年4月24日 · Lava rocks are composed of high amounts of iron and magnesium elements (collectively referred to as the ferromagnesian group) as well as calcium. Due to their chemical composition, basalts are the most abundant rock type of the ocean floor and Earth's crust, and are the primary rock layer of the Hawaiian Islands.

2021年3月17日 · The metallic lava flows travelled 10 times faster and spread more thinly than the rock flows, breaking into a myriad of braided channels. The metal also traveled largely beneath the rock flow, emerging from the leading edge of the rocky lava.
