Forschungsbohrungen (1988, Groß Pampau I & II) ergaben, dass ab ca. 7 m Tiefe der Tonschichten das mittlere Langenfeldium, ab ca. 19 m das untere Langenfeldium und ab ca. 29 m das obere Reinbekium beginnnt. Während des Hauptabbaus (Seeseite) in Groß Pampau waren ca. 17 m der Glimmertonschichten mehr oder weniger zugänglich, als Ton für die Deponieabdeckung abgebaut wurde. Anhand der aufgelesenen Fossilien (mehr als 150 Arten konnten gefunden werden) und dem Vergleich dieser Arten mit heute noch in gemäßigteren Regionen lebenden Vertretern (und deren Lebensbedingungen), geht man von einer damals durchschnittlichen Wassertiefe von 50 - 80 m aus. ... |

How long people processed galena as main ore for the production of lead is unknown. As lead inter alia used as an additive to various melts (e.g. to bronze and the salt-cementation process for gold extraction) one can assume that the properties of this mineral were known before 3000 BC. Other sources speak of a history of lead about 7000-9000 years BC back. |

He called this metal "contrefey", because it could imitate gold. Agricola did not recognize that this metal was zinc. He further observed that a similar metal, which he named from some unknown reasons "ZINCUM" arose under similar circumstances in Silesia during smelting. |
