  1. I can understand the points being brought up by land owners, but I have to disagree in some aspects. If public land is being landlocked then I believe full access should be open to all via a road. Access should not be inhibited because of the actions of just a few. That would be as stupid as saying that all access through cities need to be blocked from outsiders all because a few commit crimes and litter when they come in to the city! I also agree with the other poster who said that public lands with no access is worthless. And I wonder how these land owners would feel if I bought up all the
  2. It all depends on what part of the moon or Mars they came from. With lunar meteorites for example there is NWA482 that is grayish-white with black veins of shocked glass. Some of the Dhofar lunars are multicolored, and quite pretty. In fact I would never have thought they were meteorites looking at them. And some of the others from the moon are black with white inclusions of various sizes. A few things I have read about lunars are that the basalts tend to have a greenish cast in their crust. That lunars are not magnetic. And that they do not contain round inclusions since there is no method of
  3. I guess I used a poor choice of wording. The atomic arrangement is more random than with graphite, which is what I was trying to point out. By the way, not all diamonds form a cubic structure, and diamond films are amorphous, so they don't have a crystalline structure at all. In addition, the vacancies in the atomic arrangement will further randomize the structure. Also, twisting of the overall structure may also occur, which accounts for the colors of some diamonds. So diamonds do not always have a specific atomic arrangement. I am not sure what you meant by "unfortunately", but I did discu
  4. I would think vinegar (acetic acid), or better yet citric acid. Citric acid should not only remove the caliche (calcium/magnesium carbonates), but should also help to remove some of the rust. Citric acid can be found in health food stores, Indian markets, craft stores in the candy making supply section, online, etc. It is very inexpensive, running around $2 to 4 per pound for the powder.
  5. I realize magnetism does not make a rock a meteorite. I have already disposed of quite a number of magnetic rocks. In fact, if it were a meteorite, then the rock would seem to fit an achondrite better than any other type based on what I have learned. And these are generally not magnetic. It is a combination of things that has made me wonder. Such as the black crust over most of the rock. The relatively smooth surface, with dimpling over some of the top of the rock. The fact that all the iron in the rock has formed in balls. That the rock is not characteristic of this area, etc. I was born and
  6. I have been reading through old posts and came across this one. I wanted to clarify a few things. Diamonds are formed from graphite. Basically carbon forms in to graphite, then in to a diamond under the right circumstances. Basically high temperature in the absence of oxygen. It is generally thought that high pressure is also required, but this is not quite true. Synthetic diamonds have been manufactured for about 16 years or so under very low pressures (1/10) of an atmosphere. Originally they were formed from running methane gas past a heated tungsten coil, which knocked the carbon out formi
  7. I found this rock that I found pretty interesting. The rock is shaped like a turtle shell. Curved and smooth on the bottom. The top is grooved. There is a black crust over most of the rock. It is strongly magnetic at various parts of the rock. When I cut it open I found it contains occasional balls of iron, which are the only magnetic areas. The first attached photo shows the top. The second photo shows the bottom. And the third photo shows a cut piece showing the interior with one of the balls of iron.
  8. Just wanted to point out that the orange, as well as the grey, and the greenish grey on the rock is not a fusion crust. They are plant like growths known as lichens. They grow on rocks and break the rocks down for their nutrients. By the way, they make great antibiotics if you are ever in the middle of nowhere and need one.
