Rocks that tell our industrial history
Tunelkobako hondar zementuzko egitura. Arg. Nikole Arrieta/EHU Researchers in the UPV/EHU’s Department of Analytical Chemistry have published a study in which they analyse cemented sand formations that contain industrial waste produced as a result of metallurgical activities. These beachrocks bear … Continue reading
Collecting rocks and minerals: a recollection
Collecting is natural. We all do it to a greater or lesser degree and what we collect is motivated by many factors including value and the appeal to the eye. Rarity is often a factor, as is cost, and interest … Continue reading
From rocks in Colorado, proof of a ‘chaotic photo voltaic system’
Plumbing a ninety million-yr-previous layer cake of sedimentary rock in Colorado, a workforce of scientists has discovered proof confirming a essential concept of how the planets in our photo voltaic system behave of their orbits across the solar. The discovering … Continue reading
180-million-year-old rocks lend insight into Earth’s most powerful earthquakes
The raggedness of the ocean floors could be the key to triggering some of the Earth’s most powerful earthquakes, scientists have discovered. Geology News — ScienceDaily
Ancient rocks hold evidence for life before oxygen
This is a microscopic image of 2.5 billion-year-old sulfur-oxidizing bacterium. Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. While researchers proclaim the first half of … Continue reading
Ancient rocks hold evidence for life before oxygen
Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. The 2.52 billion-year-old sulfur-oxidizing bacteria are exceptionally large, spherical-shaped, smooth-walled microscopic structures much larger than most modern … Continue reading
