PostPosted: Jul 16, 2017 03:03    Post subject: Rockhounding in Israel - contact needed  

Hi folks!

In continuation to my previous post, one very good advice given there was to look for rockhounding opportunities close to home. Indeed, having searched the web for a while, I've discovered that there are some very nice minerals peculiar to Israel (including some only to be found here - Bentorite for example). It appears that the area near the city of Arad is full of promise, but having no experience in this area, I wouldn't want to just plunge in. So if someone here has been there, and can give tips, or knows someone local who can show us around and tell us where to start looking that would be most appreciated.

Bentonite is a typical clay found in many places. I do not know this region except for well known Timna mines and graphic granite

The OP was referring to Bentorite, the Cr(III) analogue of Ettringite, not bentonite, the clay mineral.

I have always wondered whether there are any nice specimens to be found in the Negev.

There are traces of low-quality secondary copper minerals around the area promoted to tourists as "King Solomon's mines". But considering the thousands of years of mining in the area, it is unreasonable to expect any rich bits of ore to just be laying around collectable on the surface. So be aware that the "King Solomon's mines" chrysocolla/malachite/azurite pieces in gift shops are mostly imported from the Morenci mine in Arizona, or from Mexico, Peru, Congo... not Israel. The same scam foisted onto tourists all over the world.

Micromounters can find very interesting rare minerals in the Hatrurim Formation - https://www.mindat.org/loc-2063.html - type locality for a dozen species, like the bentorite referred to in a previous post, but Israel doesn't offer much for collectors of macroscopic specimens - some gypsum, halite, chalcedony... nothing too exciting.

Peter - it was an easy mistake - I first misread the post as referring to Benitoite.

Many old mineral books list benitoite as occuring in Texas, which was one guy's misreading of bentonite, subsequently uncritically copied by later authors. ;))

Hey Alfredo! Unfortunately, we're such beginners, my son and myself, that I don't even know who micromounters are. I've read about the Hatrurim Formation and it sounds an interesting place, but how do we get there? Apparently, there's an intersection of this name on road 31, south of Arad, but somehow stopping at the junction and starting looking for minerals off the road doesn't sound like a very promising plan.
