Vernadite (MnO2·nH2O) is a mineral with a poorly ordered structure. Its synthetic analogue is designated δ-MnO2. Birnessite and vernadite are independent mineral species and cannot be described further under the same name. They have similar hexagonal unit-cell parameters, a0, but different c0 parameters. Rancieite has a structure similar to that of birnessite. Calcium bearing, 14-Å birnessite occurring in nature was first described by the authors. In addition to the todorokite having the parameters a0 = 9.75 Å, b0 = 2.84 Å, and c0 = 9.59 Å, other species of natural todorokite are known having a0 parameters that are multiples of 4.88 Å equal to 14.6 and 24.40 Å, the b0 and c0 parameters being the same.

Резюме

Резюме

Вернадит (МnO2•nН2O) представляет минерал с плохо упорядоченной структурой, его синтетический аналог описывается под названием 8-МnO2. Бёрнессит и вернадит представляет различные минеральные виды и не могут описываться под одним и тем же названием. Их гексагональные элементарные ячейки характеризуются одинаковым параметром а0 при разных значениях параметра с0. Рансьеит структурно подобен бёрнесситу. Впервые авторами описан природный 14 Å кальцийсодержащий бёрнессит. Помимо обычного тодорокита (а0 = 9,75, b0 = 2,84, с0 = 9,59 Å) в природе установлены другие тодорокиты с параметром а0, кратным 4,88 Å (14,6 и 24,40 Å). Пар аметры b0 и c0 у всех тодорокитов одинаковы.

Resümee

Resümee

Vernadit (MnO2·nH2O) ist ein Mineral mit einer schlecht geordneten Struktur. Sein synthetisches Analogon wird δ-MnO2 genannt. Birnessit und Vernadit sind zwei verschiedene Minerale und können nicht länger mit demselben Namen bezeichnet werden. Sie haben ähnlich hexagonale Parameter der Elementarzelle, a0, aber verschiedene c0-Parameter. Rancieit hat eine dem Birnessit ähnliche Struktur. Das natürliche Vorkommen Calcium-führenden 14-Å Birnessits wurde zum ersten Mal von den Autoren beschrieben. Außer dem Todprokit mit den Parametern a0 = 9,75 Å, b0 = 2,84 Å, und c0 = 9,59 Å sind andere Arten von natürlichem Todorokit bekannt. Sie haben a0-Parameter die ein Vielfaches von 4,88 Å sind, wie 14,6 und 24,40 Å. Die b0- und c0-Parameter sind dieselben. [U.W.]

Résumé

Résumé

La vernadite (MnO2·nH2O) est un minéral ayant une structure pauvrement ordonnée. Son analogue synthétique est designé δ-MnO2. La birnessite et la vernadite sont des espèces minérales indépendantes et ne peuvent plus être décrites par la même appellation. Elles ont des paramètres de maille hexagonale pareils, a0, mais des paramètres c0 différents. La rancéite a une structure semblable à celle de la birnessite. La birnessite 14 Å contenant du calcium, trouvée dans la nature, a été decrite pour la première fois par les auteurs. En plus de la todorokite ayant les paramètres a0 = 9,75 Å, b0 = 2,84 Å, et c0 = 9,59 Å, on sait que d'autres espèces de todorokite ont des paramètres a0 qui sont des multiples de 4,88 Å égal à 14,6 et 24,40 Å, les paramètres b0 et c0 étant les mêmes.
