Summary
| Description |
Eesti: Eesti põlevkivimaardla tootuskihindi läbilõige Põhja-Kiviõli II karjääris. Põlevkivi tootuskihindi moodustavad põlevkivikihid A...F1 ühes nendevaheliste lubjakivikihtidega, kuigi mõningatel juhtudel kaevandatakse ka põlevkivikihte F1, G ja H. (fotol nähtavad aga märkimata) Pildil on märgitud kihtide piirid ning nende tähised, põlevkivikihid suurtähtedega ning lubjakivi vahekihid kahe suurtähe kombinatsioonina, mis viitab kihi paigutusele põlevkivikihtide vahel. Katkendjoonega tähistatud piire on keerulisem pildilt määrata ning on seetõttu hinnangulised.
Stratigraafia: põlevkivi tootuskihind kuulub Viivikonna kihistu Kiviõli kihistikku (indeks O3vvK). Kronostratigraafiliselt Ülem-Ordoviitsiumi Kukruse lademesse (globaalse kronostratigraafia Sandby lade).
English: The productive layer of the Estonian oil shale deposit as seen in the Põhja-Kiviõli II opencast mine. The productive layer is made up of oil shale layers A through F1 together with the limestone layers in between. However, in some cases, layers F2, G and H (visible in the image, but not labeled) are also mined. The oil shale beds are marked on the image with capital letters, limestone layers are labeled with a combination of two capital letters, indicating at their location within the productive layer. Dashed lines indicate layer boundaries, which are harder to distinguish and are thus approximations.
Stratigraphy: the productive layer of the Estonian oil shale deposit is part of the Kiviõli Member of the Viivikonna Formation. The formation belongs to Upper-Ordovician Kukruse Regional Stage (global Sandbian Stage). |
