Facies and Classification Lists
Nine branches of the Collections Tree hold the classification schemes a project logs against. They are ordinary named lists: each entry has a name, a colour and often a symbol or icon, and the logging and interpretation tools offer the entries as choices. Setting them up once at the start of a study is what makes logs, panels and paint layers comparable across it.
Entries are added with New on the branch header and edited in the
Properties panel. A whole scheme can be shared between projects with
Export and Import on the branch header — a facies library is a .dfl
file.
| Branch | What the entries are | Where they are used |
|---|---|---|
| Facies | The project's facies scheme: name, colour and fill. | The active facies applies to each new log unit, and to paint overlay layers on a mesh. Create Colourmap on the branch header builds a colour map from the scheme. |
| Associations | Facies associations. Each association lists the facies assigned to it, shown as children in the tree. | Grouping facies into associations for logs and panels. |
| Grainsize | The grain-size scale: the classes down the log's grain-size axis. | The profile axis of a sedimentary log, and the default grain size of a new unit. |
| Generic Classes | User-defined classification lists. Each class is a named list with its own entries, shown as children. | Any attribute of a log unit that the fixed lists do not cover. Also carries the carbonate classifications. |
| Base Contacts | The kinds of contact at the base of a unit: sharp, erosive, gradational, and so on. | The base-contact property of each log unit. |
| Lithologies | The lithology scheme. | The lithology of a log unit. |
| Sed Structures | Sedimentary structures: ripples, cross-bedding, bioturbation, and so on. | Structures recorded against a log unit; drawn with the structure's icon. |
| Sed Fill Styles | The fill patterns a log unit can be drawn with. Rescan Fills on the branch header re-reads the fill files from disk. | How units are shaded in the 2D log and correlation panels. |
| Palaeo | Fossils and other palaeontological entries. | Fossil occurrences recorded against a log unit. |
See the Sedimentary Logging guide for how these lists are used while logging, including the Defaults panel that sets what a new unit starts with and Replace Facies for changing a scheme after the fact.
Context menus
Every branch here shows the standard group menu on its header and the standard item menu on its entries, both listed on the Standard Item and Group Menus page. Two branches add one command each: Create Colourmap on Facies, and Rescan Fills on Sed Fill Styles.
