Quartz, Hematite
Ganzhou, Jiangxi, China
Dimensions: 7 X 5.2 cm |
Hi Richard, this is a very beautiful specimen from China (in Collection of Richard & Jensa Arseneau), but for sure not from Ganzhou or anywhere else in Jiangxi Province. These combinations of quartz with fragile hematite blades are from Guangdong, from Jinlong Hill (this is where the famous ones with vivid red or yellow coating are from) or from Lechang Mine. According to your photos, I'm more than sure that your specimen is from one of these two localities, the specimens are quite unique and distinctive. I think others here can confirm that.
Regards
Tobi

P.S: Just after my comment I saw the locality was changed to Jinlong Hill ;-) |

That is interesting! I will certainly take the word of the knowledgeable people on this forum. I based the locality off of two specimen cards that came with the piece. A dealer who is both a geologist and avid collector obtained this specimen as part of a collection he recently purchased. Both cards say "Gan Zhou Mine, Province of JiangXi, China"
Thanks for the heads up, I will correct my records.

Hi Richard, what you experienced is a problem that often occurs when Chinese minerals come to the (Western) market: There is many wrong or simply unknown locality information, thus the dealers often give wrong information because they want to sell their stuff and you know the old "rule": Better some random locality on a label than none at all ... :-(
The label you have is a typical example, it even features TWO mistakes: It is not only wrong that this Jinlong (or Lechang) specimen is from Ganzhou in Jiangxi Province, furthermore there is no "Ganzhou Mine", for Ganzhou is a whole district. There are several mines in this area, some are well-known like Xiefang Mine (famous for nice fluorites, golden barites and pyrite "balls") or the Dayu County with its several mines, but none of them produces similiar specimens like that. So I wonder that the former owner, when he's a geologist and avid collector, wasn't able to find out the correct locality for such a distinctive specimen. I guess he had no knowledge about Chinese minerals (or maybe he was not introduced in the use of the internet ;-)) because these specimens are actually distinctive.
However, you have the correct locality now, or at least the two possible ones, for it could also be from Lechang instead of Jinlong. You could label the locality simply as "Guangdong Province, China", this may be not very precise, but 100% correct :-)
Best regards

Thank you Tobi, this kind of information is the reason I love this forum. The dealer I bought from collects mainly Canadian minerals and often self-collected. So I suspect that the old card was just copied without any investigation.
Speaking of Canadian minerals, I have a couple of new specimens I will share when I get around to photographing them. :) |

Hi Richard, this is a very beatiful specimen from China (in Collection of Richard & Jensa Arseneau), but for sure not from Ganzhou or anywhere else in Jiangxi Province. These combinations of quartz with fragile hematite blades are from Guangdong, from Jinlong Hill (this is where the famous ones with vivid red or yellow coating are from) or from Lechang Mine.

This is an interesting topic and that's why I moved it to this right section "Improving the FMF Data Base of localities" created precisely to discuss these kinds of things in order to improve our localities data base.
In this case my vote is for Jinlong Hill but it is true, as Tobi well said, that the Lechang ones are not so different, so, to avoid errors I assigned it just to "Guangdong Province" (see: https://www.mineral-forum.com/message-board/viewtopic.php?p=66727#66727 ) and with this we can be sure that no mistake is made.
Thanks Tobi (and Richard) to help to improve our data base. |
