THIS POST WAS ORIGINALLY PUBLISHED 3-4 YEARS AGO AND HAS BEEN IN DRAFT FORM FOR AN UNKNOWN TIME. IN SCROLLING THROUGH MY POSTS I DISCOVERED IT AND THOUGHT IT NEEDED TO SEE THE LIGHT OF DAY.

And the idea of just wandering off to a cafe with a notebook and
writing and seeing where that takes me for a while is just bliss. J. K. Rowling
In this time of the Covid-19 pandemic and self-isolation my mind wanders, as do the minds of several rockhound friends. That wandering activity is not a “bad thing” as most of us have some degree of ”pandemic depression. Listen to the advice of newscaster Diane Sawyer, I've always found a cure for the blues is wandering into something unknown, and resting there, before coming back to whatever weight you were carrying. Between wandering I try to keep busy with other chores (I am tired of raking leaves) and activities. I read a new book about every three days or so, play with the minerals, devour the newspaper, write letters to the editor (few are published), write/read several hours a day, watch a little TV (mostly older “happy” movies with such phrases as: Jake: That Night Train's a mean wine) , exercise a little, and listen to the oldies music channel : Elwood: What sort of music do you usually have here? Claire: Oh we got both kinds, We got country, AND western. As you can probably surmise, I have a weird sense of humor and enjoy watching the Blues Brothers: I have four fried chickens and a coke. OK you need the see the two movies to understand the humor of Jake and Elwood!

My days are not strenuous but are not too exciting either; however, we have food and shelter and family wellness and for this I am happy. And, as you might suppose I am “retired” with Social Security and do not hold an actual working position and that certainly skews my activities and thinking. One of the good things about my life is that I am learning much, not only about minerals, but about the world in general, how a virus operates, a new word every day, how bars form a significant part of our social wellbeing, about economics as the price of groceries heads upwards while gasoline trends down, and how scientists are taking a bum rap with this pandemic. Personally, I am waiting for scientists to conquer the Covid-19 pandemic.

Oh, so lonesome for you
Why can’t you be blue over me

Bill Mack but a big hit by LeAnn Rimes
Well it's one for the money, well it's two for the show
Well it's three to get ready, now go, cat go
But don't you step on my blue suede shoes
Well you can do anything but lay off of my blue suede shoes

What about your favorite Blues genre or blue in the lyrics song? Do rockhounds have a favorite? Well, as an ole rock and roller like me (my age is certainly showing) Carl Perkins and Mitch Ryder are tough to beat. But my all-time favorite is the Delmore Brothers, “Blues stay away from me.” The music is very haunting (probably because of the tenor four string guitar and the harmonica of Wayne Raney, but it brings back memories of my youth when Saturday night dances were scattered across the rural areas of Kansas. Those dances usually presented a “big band” sound, or “hillbilly” music; rock and roll generally was confined to high school dances. In the days before cable TV high school or “town team” sporting events, and local dances were the major sources of entertainment in rural parts of our country. Yea, I know very few readers have heard a recording by the Delmore Brothers! But consider they were stars of the Grand Ole Opry in the 1930s and wrote more than 1000 songs. Perhaps Bob Dylan summed it up best: “The Delmore Brothers, God I really loved them! I think they’ve influenced every harmony I’ve tried to sing.” So, there you know some of my strange secrets!

Maybe you have a favorite "blue" movie? Who could forget The Blues Brothers--It's 106 miles to Chicago, we've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses. Hit it. Perhaps Blue Velvet, The Blue Lagoon, Blue Hawaii, or the IMAX film the Blue Planet? But again, I am showing my age.

So, what about your favorite blue mineral? I presume a large segment of the rockhound population would immediately state azurite, the copper carbonate. Others might spout turquoise or zoisite (tanzanite), opal, aquamarine, or numerous others. So, it popped into my head, since we do not have club meetings, ask members of the CSMS to send me photos of their favorite blue minerals. I was expecting about 50 bored rockhounds to flood the emails! But it appears that most members must be occupied with other important activities and I sincerely thank Kevin Rockhounding the Rockies Witte, the guy who knows about fluorite Bob Landgraft, and Mr. Lapidary Tool Man Bill Kern. But most of all I thank John Emery, the fantastic Pick & Pack Editor for allowing me to add rather frivolous material to a mostly serious newsletter. However, the activity perked up my mind and perhaps readers might find a little humor to help put a damper on “pandemic fatigue”. So, thanks John.

I
have espoused my views on blue minerals with numerous Blog postings and today
have a couple of new, blue, copper arsenates: guanacoite and
arhbarite. You aren’t familiar with them? Neither was I until I
found them in a dusty drawer of a small rock and mineral store and started
reading.
Arhbarite,
a hydrated copper magnesium arsenate [Cu2Mg(AsO4)(OH)3],
gets its “strange” name
from the Type Locality in Morocco, the Arhbar (orAghbar) Mine. It
usually has a dark blue color, a vitreous to sub-vitreous luster, a blue
streak, and often forms as botryoidal cluster of radially grown
crystals. However, at times the crystals are so tiny that the
mineral appears massive. Arhbarite forms in the oxidized zone of polymetallic
ore deposits due to percolating hydrothermal fluids and is usually associated
with other copper arsenates such as conichalcite and
guanacoite. Arhbarite is a rare mineral only found in two
localities, the Type and in Guanaco in Chile.
In fact, the “strange” name for the second mineral, guanacoite, comes from its Type Locality in the El Guanaco Mine (Atacama Desert, Chile). The mine produces gold (primary commodity), silver, and copper (chalcocite, bornite, enargite, and covellite) from Eocene rhyolite. It is both a subsurface and surface mine. In addition, the Mine is a source for numerous and colorful blue and green copper minerals, including copper arsenates.

is similar to arhbarite in that it is a hydrated copper magnesium arsenate
except it has additional water [Cu2Mg3(AsO4)2(OH)4-4H2O].
It has a pale blue to blue color, a white to light blue streak but most
important for identification, it usually occurs as prismatic, acicular to
bladed, translucent crystals. Guanacoite is often found as tiny
blades lining, or associated with, vugs of arhbarite. Again, it is a
rare mineral only known from the Type Locality, Morocco, and Spain. The copper zinc carbonate, rosasite (R) and the arsenate mixite (M) from the Tintic district.. FOV ~ 1 cm. Photo: Mike Nelson. |
