    All the gold in California lies in "A bank in middle of Beverly Hills in somebody else's name".

    Oh wait back to the topic...

    Most of the gold in California lies in "The Motherlode" mining district below 5,000' elevation between Downeyville, and Yosemite. It occupies just about all the streams in that region. Plus there is a north-south seam between Auburn and Jackson where we find the really deep hard rock mines (several thousand feet deep) There they mine gold bearing milky quartz in granite (only one mine is operating today). The Nevada side of the Sierras has a lot in alluvial deposits. Most of the small towns in the Motherlode district had 10-20 thousand people during the gold rush. Now most of the same area is bed-room community to Sacramento (with all the hell of people discovering their house is built atop a collapsing gold mine).

    I have heard a theory that the gold was emitted by the mid oceanic ridge, and deposited on the sea floor. That sea floor was smashed onto the edge of California by accretion something like 250MYA (Million Years Ago). A lot if it was mixed into magma which intruded into the accreted crust as granite plumes, the gold being concentrated in quartz veins. The band being a portion of the sea floor that was not sub ducted, but instead acreted into the crust.

    About the diamonds, yes being very hard, they persist well and are concentrated in streams. But unlike gold which is 6-8 times denser than granite and basalt, diamonds look like quartz, and aren't heavy enough to seperate from basalt by weight.

    There are apparently diamonds almost everywhere, or some people think. Here in Northern California, they are reported to be found near where gold was discovered in Placerville California (Actually Smith Flat). I found what appears to be a kimberlite pipe in Northern Oregon. This is kind of a unique area, where volcanic islands were partially subducted and merged with the Coast. I don't know if diamonds will be found there, I've read they only appear in any meaningful quantities in about 2% of Kimberlites. Even then, the number of diamonds is really low.


    If you are interested in searching for diamonds, join a local gem society. Ask the members about UV lights. They cost a few hundred, even for low power battery operated lamps, and there are some pretty crappy ones too. Be sure to wear eye protection, because UV light will trash your eyes. But most diamonds ( and a lot of other unique minerals ) fluoresce.

    Mantle rock is not magma. Mantle material is usually very hot because it is (A) very heavy, and (B) usually covered by a layer of insulating lighter crust material. The crust is 3-18 miles thick. Magma is usually crust material that got pushed down into hot mantle material and melted. The crustal material magma being lighter than mantle wants to rise above the mantle magma. So usually we have an intrusion of lighter crustal magma being forced through the mantle. So we've never seen mantle material exposed before. Some small samples of solid mantle material have been carried up by some of the cooler type volcanoes. This is how we get diamonds and peridots. Read about Kimberlite pipes.

  11. Re:lab work on Adventuresome or "Hands On" Careers in Tech? · · Score: 2, Interesting

    I agree with semiconductor R&D, as being very rewarding.

    I started as a "validation tech", pushing parts through the handlers. This was destructive and non-destructive testing on big lots of parts. We get the parts straight out of the fab, test and keep only the good ones. Then we split this huge lot into several lots, and each sub-lot goes to a different "stress", maybe ESD, steam chamber (can we force moisture into the package), etc. Later we test the part to see how many we killed. It was a good place to start, and I dazzled some Engineers.

    I was asked to move into a Product Engineering Group. In product engineering there are lots of different jobs. Right now, I do "Design Validation". Remember that transistors are 3-dimensional structures made with a photo-graphic process. So with just a little variation in the fab (Yes Virginia, this does happen), the transistors behave differently. My job is to measure different power, timing on different fab lots. This involves very high speed test equipment, and lots of PERL scripting. I run on three different types of testers. I setup the testing process and make it fully automated (PERL in UNIX). Running the actual job gets passed to a validation group (see the second paragraph), and I move on to incorporating a new test type (semiconductor R&D is never static). I still own the old jobs, and as long as they run fully automated, I just reduce the data, and publish a data report.

    Semiconductor R&D has a large variety of tasks, in and out of different labs, lots of different testers, some programming, some data analysis, some teaching (test methods), some hardware work too.

    If a semiconductor companies R&D ever becomes static, it's time to go short on that stock.

    Is there some possible critical variable that has not yet been identified?

    I really hate fluorescent lamps.

    I've got fluorescent in the garage ("The shed" for our Aussie and Kiwi friends). It really sucks... Since I don't regularly heat the garage (who does?), when it's cool, the lights don't want to come on, and when they do, there's a lot of flickering.

    Then there is the whole disposal problem, how do you dispose of a four foot long fluorescent? Crush it up, pack the pieces in a heavy duty paper bag, and send it off to the local transfer station (It later ends up in a (probably un-regulated) land fill on a Nevada Indian Reservation).

    Is there a lamp monopoly or something going on? I don't understand the need for fluorescent junk... Replacement LED lamps for the household should cost less than an incandescent.
