Hallo liebe Sammlerinnen und Sammler,

Trotz Corona hatten sich letzten Donnerstag 19 Gruppenmitglieder und zwei Gäste im Naturmuseum Dortmund eingefunden.

Der Vortrag über die Zeche Friedrich der Große - Herne war ausgezeichnet. Wir wurden vom Gründungsjahr 1850, wohl gemerkt
erstes Abteufen eines Schachtes war erst 1870, über die verschiedenen Abbaujahre bis hin zur Schließung im Jahr 1978, durch die Zeit
geführt. Sehr ungewöhnlich waren die detaillierten Karten und Funde, siehe das Bild unten. So genau sieht man im Ruhrkohlenbergbau äußerst selten.

Schade das nicht noch mehr Gäste den Weg zu uns gefunden haben. Wir hätten noch Platz gehabt.

Glück Auf!

Sebastian

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN SEPTEMBER 2021

An end-member formula for humite, Mg7(SiO4)3F2
The humite polysomatic series consists of a set of minerals with the general formula n[Mg2(SiO4)]⋅Mg(OH,F)2, with n=1, 2, 3, or

4. The valid species and their corresponding chemical formulae,
taken from the current IMA List of Minerals, are as follows:
(n = 1)
Norbergite, Mg3(SiO4)F2
(n = 2)
Chondrodite, Mg5(SiO4)2F2
Hydroxylchondrodite, Mg5(SiO4)2(OH)2
(n = 3)
Humite, Mg7(SiO4)3(F,OH)2
(n = 4)
Clinohumite, Mg9(SiO4)4F2
Hydroxylclinohumite, Mg9(SiO4)4(OH)2

The only species without an end-member formula is humite,
Mg7(SiO4)3(F,OH)2, which has both fluorine and hydroxyl within the same brackets. As in the whole series a rootname without a prefix is used for the fluorine end-member, whereas the same rootname with the prefix ‘hydroxyl-’ is used for the hydroxyl endmember, the formula Mg7(SiO4)3F2 has to be assigned to the mineral humite. This is an executive decision taken by the officers of the IMA-CNMNC.

Renaming of gismondine
Following the report of the Zeolite subcommittee, after the approval of the new mineral IMA 2021-043 – gismondine-Sr (see this Newsletter), ‘gismondine’ becomes a series name. Accordingly the mineral previously known as gismondine is renamed gismondine-Ca.

IMA 20-F: Chabournéite group
Proposal 20-F is accepted, and the chabournéite group is established. The group includes the minerals chabournéite, protochabournéite, dalnegroite, shimenite and dewitite. All members of this group are triclinic, space group P1, with the exception of dalnegroite, which has space group P1.

The ideal formulae of protochabournéite and chabournéite are
revised as follows:
Protochabournéite – Tl4-xPb2+2xSb20-x-yAsyS34 (with 0.02 ≤ x ≤ 0.34, 5.71 ≤ y ≤ 6.69).
Chabournéite – AgzTl8-x-zPb4+2xSb40-x-yAsyS68 (with 0.00 ≤ x ≤ 0.40, 16.15 ≤ y ≤ 19.11, 0.04 ≤ z ≤ 0.11).

IMA 21-D: Redefinition of beraunite and discreditation of eleonorite
Proposal 21-D is accepted. The formula of beraunite is revised as Fe3+6(PO4)4O(OH)4⋅6H2O, based on new EMPA, Mössbauerand SCXRD data obtained on type material. Eleonorite is discredited, as it is identical to beraunite.

IMA 21-E: Redefinition of minyulite
Proposal 21-E is accepted, and the formula of minyulite is redefined as KAl2(PO4)2F⋅4H2O, based on new EMPA data obtained on holotype material, which confirmed that the mineralis (OH)-free and has F as a species-forming constituent.

Hallo Holger,

es lag an der Übermüdung. Das kenne ich schon von 2016. Die Ereignisse im UKJ  setzen mir zu. Habe den Quatsch gelöscht und werde mich erst einmal zurückziehen.

Tja, leider sind viele Hauptstraßen inkl La Laguna teilweise zerstört. Auf Teneriffa und wie es aussieht auch auf La Palma stauen sich die Wolken und für La Palma ist Regen gemeldet. Derzeit ist mir das Buchen von Fähre 200eus für zwei Personen,. Leihwagen 100eus und eine Übernachtung 80eus zu kritisch. Wer weiss was da noch gesperrt wird...
Anbei ein Bild nördlich vom Teide aus aufgenommen.rechts am Horizont ist der roque der los muchachos und links die Wolke ist der Vulkan. Mal weiss Mal dunkel...

Das mit dem Platz ist ja auch kein Problem, bei den wenigen Händlern die da waren. Gab ja noch viele leere Stände. Aber will nicht meckern, ein kleines München ist besser als kein München.
