Loud detonations were reported as the fireball flew out of the northwest. Moments later, the largest known enstatite chondrite arrived on Earth. In specific, Abee is an impact-melt breccia, EH chondrite. by Jim Tobin Over the next few months there will be a lot of information and articles on the Moss Meteorite. But, I thought amongst other things this month that I would share a few thoughts and a couple photographs of Moss. On July 14 over Norway a meteoroid fragmented and as of now about 3 kgs have been recovered. It is being referred to as a CO type carbonaceous chondrite by Robert Verish Meteorite collectors may find these articles from the past year's issues in Mineral News of some interest. It was about this time last year that I ran a series of articles about mineral collectors, and with their concern about the decline in their hobby and in the value of their collections, concerns which they expressed in articles published in the monthly newsletter, Mineral News. I drew parallels to show the similarities between meteorite and mineral collectors, by Tom Phillips When Martin said that this month he wanted to feature an ordinary chondrite (H6) I figured "an H6?" OK but why? A H6 typically doesn't have many features to look at because the chondrule structure is dramatically altered. by Martin Horejsi I remember once when a travel brochure caught my eye. It was for the Head-Smashed-In Buffalo Jump in Alberta Canada. Having grown up in Montana, I was quite aware of the concept of a buffalo jump, but still, the bold yet truthful marketing surprised me. No sugar coating here. So when I first heard about the circumstances of the fall of the Valera meteorite by Jim Tobin The Earth's atmosphere is struck constantly by particles from outer space. We call them meteoroids and they can range in size from the microscopic to the size of a bus. The large one being exceedingly rare events. But several times a year there is a flurry of excitement in the meteorite community as reports of a fall of stones is received. Right now the focus of attention is Norway by Tom Phillips & Martin Horejsi One year ago, it was one of the rarest materials known. Now, (due to one good size find?) it seems to be showing up under nearly a dozen names that may be paired. I chose NWA 2965 because my supplier said it was and because the majority by Martin Horejsi At the time Romania was securing its autonomy from the Turkish Ottoman Empire, the second documented meteorite fell onto Romanian soil. On October 11, 1857, a glowing fireball crashed through the midnight sky with booming detonations. A priest found the stone forever preserving the space rock for future generations. Technically, a single 16.25kg mass was recovered and later named Ohaba. It is classified as an metal veined H5 chondrite. In case you have never heard of Ohaba, it might be because even though you are reading this almost 150 years after the fall, 97% of the original mass is still is part of the meteorite collection of the Natural History Museum in Vienna, Austria. If you do the math, that only allows for about 570 grams for the rest of the entire world's collecting needs. Luckily there is a rich supply of Mocs, Romania material to serve the collecting community's hunger for Transylvanian meteorites... by James P. Tobin I spent last weekend combing the house and office getting every predigital photograph of Meteor Crater together. Now I have to scan the ones that will go into the new book. But I have many great pictures that don’t show anything discussed so I will share just a few with you this month. This first photograph is of Canyon Diablo just west of the crater. It is of course the geographical feature that the meteorites of the crater are named after. The canyon’s vertical walls... by Robert Verish This has been a hotter than average summer, here in the southwestern U.S.A. And already there has been an above average number of reported deaths having occurred in the desert this summer. Although not all of the coronor's reports have been made public, it is expected the cause of death in most cases will be "dehydration" and "heat stroke". Maybe before going out on that next trip to the desert to search for those meteorites, this would be go time to review some safety precautions for averting situations that could bring about "dehydration" and "heat stroke"... |
