And, of course, there is now plenty of time to work on photographing and cataloging new minerals. I acquired this Mexican apatite last February in Tucson from the Rock Currier collection. I understand that he got it in 1972.
Mineral: | Fluorapatite |
Locality: | Cerro de Mercado Mine, Cerro de los Remedios, Victoria de Durango, Municipio Durango, Durango, Mexico | |

Dimensions: | 7x6x6 cm overall size |

One of my walks in the countryside, a few meters from home, within the Montseny natural park,(Barcelona province), I have the mountain nearby, we have been lucky to be confined in this environment,

Hi to everybody!
Here is the situation in what is now the 4th most affected country in the world as a number of deaths. As you know, Brazil has recently overtaken us in this very sad grading. What about today? In Italy we had 65 deaths (32 in Lombardy, my region), 283 currently hospitalized with intensive therapy (107 in Lombardy), 4729 currently hospitalized (2708 in Lombardy), 34730 currently positive to virus (19319 in Lombardy). As you can see, the most serious situation is here in Lombardy and we all have to be careful (but unfortunately the biggest majority of people aren't). But we can see a small light at the end of this tragic tunnel. The large amount of military lorries containing mortuary coffins and going to the middle-south of Italy in order to burn all of those poor bodies is not fiction, it really happened! No ceremony, no one last greet, no burying! Incredible but true!
Ok, let's hope it will come to an end as soon as possible, so that we all can meet at our mineral expositions!
Greetings from Italy by Riccardo.

One of the things about being stuck at home for around 11 weeks now is that one finds lots of chores around the house that need doing. One that I've started working on is sorting through years of accumulated stuff in our garage and throwing things away. A couple weeks ago I came across a box of old Rogerley specimens, likely from around 2001-2002. Most were very low quality, and are likely things that I did not think were even worthy of trying to sell in wholesale flats. Among the lot was a cluster of untwinned purple crystals of the sort that we would occasionally find in small cavities while driving tunnel on the main vein. These cavities were usually in solid rock, as opposed to the flats where the green fluorite came from, which were fairly broken up and easier to collect. We never got very many of these purples, largely because by the time we would discover a cavity the nearby use of explosives would have already turned the fluorite crystals into cleavage fragments.They weren't worth nearly the money that the greens were, so we didn't worry about it, too much. But here was one, still coated in it's pocket mud.After a bit of cleaning I think it turned out fairly well. A nice little souvenir from times past.
Mineral: | Fluorite and Quartz |
Locality: | Rogerley Mine, Frosterley, Weardale, North Pennines Orefield, County Durham, England / United Kingdom | |
|
Dimensions: | 6x6x4 cm overall size |
Description: |
Likely recovered around 2001 from a small cavity on the Greenbank vein. |

Our laptop in lock down, guarded by the cat, haha, In the Netherlands slowly (and wisely) measures are eased, but this dreadful virus is still around.
Nnevertheless nature is changing from springtime to early summer. This butterfly was warming up in the sun, the name in Dutch is: little fox. Wish you all the best, stay strong and healthy!

We are approaching summer. Nature is wonderful...

Sunny day after a lot of rains.
Walking among other persons is part of my recovery process. Like many persons I'm a collateral victim of the covid-19, unable to go out where there are people even with all the recommended precautions and with an under control pandemic. It's going to be a long process.
Have a nice day and keep safe.

Good one, Vic. Marcie and I laughed our arses when we saw your mug shot. I'm not far from that look myself, complete with the "Here's Johnny!" greeting. Maybe this will start a new "look" and become quite the rage!

Today it's the Swiss National Day but I think one of the strangest in the history of the country with few manifestations.
For us, a little walk along the river Vièze in Morgins with a ferruginous source in the hearth of the Swiss Alps.
Hope everybody is safe and have a nice weekend.

Even if the tourists think they are bulls but no, they are cows. During the spring they naturally fight to know which will be the queen to the herd. |

Not a good idea to be out in the field with pointy bars sticking out of a sack full of steel. So, the Faraday cage of the control shack seemed like a good idea.

Coronavirus COVID-19 in the atmosphere ?
Although having been a teacher-researcher in chemistry at the university ULiege, I did not understand clearly the physical state and the means of transport of the virus in the atmosphere.
Today, talking about the Covis-19 has become a trivial article subject after a year of the invasion of this enemy.
By the presence of oxygen and water, the Earth's atmosphere is quite complex. The character of this atmosphere is essentially oxyphilic.
However in essence, virus particles constitute rather a non-polar organic medium.
Moreover, I had never seen an explanation of the selection of the hydro-alcoholic gel as the most recommended disinfectant, nor of the correlations between climatic parameters and the stability of the virus. It is for these reasons that I thought a lot about it while writing…..

Hi Don,
I am not a medical professional, nor even an amateur.
It was a choice I made when I was 18 and I have never regretted it.
Professional chemistry (and physics) has given me much more satisfaction.
I did not read the medical references because I am not able to measure their credibility.
What I see are often long sentences and statistics that mean nothing to me.
Anyway, do you know of an article that explains how the virus is transmitted in the atmosphere? How does hydroxyalcoholic gel work?
What interests me is the "view of the physical state" of the virus, at least in a virtual way. In other words, how do the little "hedgehogs" float in the air?
Many thanks.

Hello Roger,
This is the way I understand the SARS-CoV-2 infection.
Viruses are present on aerosolized mucosalivary droplets expelled when an infected person speaks, coughs or sneezes. When another person comes along and inhales the aerosolized droplets, the virus enters the nasopharyngeal or oral cavity (mouth-breather) and attaches to the ACE-2 receptor on the surface of the cells of the respiratory tract including the alveoli. The ACE-2 receptor is the way the SARS-CoV-2 virus enters the human cells where it uses the host cells machinery to replicate. At some point the host cell bursts and many viral particles are released from the infected cells to infect other cells. This is why the antibody cocktails are important early in the process i.e. to reduce the viral load.
Alcohol kills germs through a simple chemical process known as denaturation. Denaturation occurs when alcohol molecules bond with the fat membrane encasing a virus or bacteria cell. As the fat membrane is broken down, the inside of the cell — including all of its critical components — becomes exposed.
This may be a simple answer to your question, but as you know I have a simple mind.
Regards,
Don
