Material merged from coring talk page[edit]

Merge proposal[edit]

I think Coring and Core sample would go quite well together. Does anyone have any reason the two shouldn't be merged? TastyCakes (talk) 23:22, 28 January 2009 (UTC)

The Coring page within Wikipedia has nothing to do with sampling. —Preceding unsigned comment added by (talk) 16:13, 14 January 2010 (UTC)
Yes, the articles were merged and the coring article no longer mentions this type of coring, like it used to. TastyCakes (talk) 17:18, 14 January 2010 (UTC)

Multiple Issues[edit]

Since I'm sitting on a mobile offshore drilling rig, reading the proposal for coring on the next well, I suppose I'd better go through this article and address multiple issues I see on first read-through. The notes below are as much for my own guidance while modifying the article.

  • The materials used in construction of core-cutting equipment are largely irrelevant.
  • Methods - at least one numerically frequent type of core is note addressed - "percussion cores", known in the oil industry by various brand names and acronyms such as "SWC".
  • The "management" section (perfectly reasonable in itself - that's why we have a core programme before we even get the rig to the location!) contains "techniques" information that would probably be best broken out into a separate section.
  • Layering and stratigraphy is often irrelevant to cores cut for mineral projects. (I see a break-out there into dendrochronology, which is perceptive.)

I'll make some alterations in respect of these issues and see what other people have to say.

Comments on my own changes[edit]

  • Added several different techniques, with discussion of their suitability for different circumstances and limitations on target materials.
  • Excised the "methods" material from the "management" section ; that looks like a cut'n'paste from somewhere else anyway. Discussed the data necessary to relate the core sample to the (geological) structure that it samples. The importance of record keeping.
  • The "historical" matter in the "management" section is ... well, it's now a separate section.
  • Processing techniques ... I've writen something, but the network engineer has just come into the office to do "stuff". So that's me finished.

The history of core sampling in this article gives no dates and does not tell who did the first core sampling. — Preceding unsigned comment added by (talk) 12:11, 8 October 2011 (UTC)

""Granitic" rock core from stillwater igneous complex, Montana (from a spoil pile)" captioned picture in "Methods" Section[edit]

Please review this caption for correctness.

The core in the picture does not appear to be granitic. Is it a gneiss?

To me, it looks more like a gabbro or a norite.

What do you think?

Thank you for your time,
