Hello! This is Secret Aging Man posting as a guest, for the first time on W2W's blog. My dear W2W insists I do something productive and join her blog as a periodic “guest blogger” and share wonderful tidbits of knowledge about rocks. Well, I’m not sure if anyone out there really cares much about pretty rocks and minerals or if joining in a cyber-conversation is really the kind of productivity I need. Given my recent layoff (first time in 29 years), perhaps remembering and recording some of my past hobby experiences will indeed provide a creative release and reduce the stress of living in these troubled times.
Maybe a little background information is appropriate to include here. I am 51, married for the past 29 years to Walk2Write, parent of two grown children and grandparent to one rockin' 2-year old boy (hereafter called "Pebble Pup"). My professional background as a geologist has see-sawed from environmental professional to oil exploration geologist. I used to joke that I could go out and find the oil deposits, then switch hats and charge for cleaning up the mess we made with all the oil contamination! Really – I’m kidding here. Please don’t take everything said too seriously. I am all for being a good steward of the environment, but there are always at least two sides to every story.
My love for rocks all started when I was about six years old and just couldn't stop picking up shiny stones from the family driveway and stuffing them into my pockets. The obsession got so bad and the pile in my bedroom floor so big, that my parents finally found a fellowship of rock-lovers (our regional rock club) to train their young son in proper rock collecting techniques and identification. We found out that the shine and color a lot of the driveway rock was because it contained the minerals fluorite, sphalerite, and galena. Seems our home in Southern Illinois was paved with limestone aggregate from the "spar" mines, located about 60 miles to the southeast, in Rosiclare. My first rock collecting site turned out to be a pretty good one, if only ten feet from the front door!
The photo shows what I have left of the once vast family mineral collection. About 95% to 98% of our collection was sold back in the early ‘90s to pay for a necessary home foundation “prop-up”. Seems my Mom’s house was situated directly over the underground workings of a Southern Illinois coal mine and the surface of the ground slowly sank, or subsided, in response to the sloughing of the old mine pillars. This is a common malady in areas where subsurface coal mining is prevalent and can be compared to “sinkholes”, for those not familiar with mining, but perhaps living in areas of cave topographic expressions. I will discuss fluorite at greater length, in my next post.
