  1. Archean Paleoenvironments

    A great lecture and lengthy lecture about Archean paleoenvironments, tectonics, geology, and some paleontology is: Archean Surface Conditions Ideas in Science By Christoph Heubeck - RED18 Published on Mar 12, 2018 http://astrobiovideo.com/en/video/175 https://www.youtube.com/watch?v=yNEkQ8KV-aQ It begins: "Here is the the principal take-home take-home message. All right. We know very little about the early Earth and and therefore it's such an interesting thing to talk about. We do know a bit right. We know just enough to talk endlessly about it but we do not know enough to supply you with firm numbers that would put any issue too firmly to arrest." Yours, Paul H.

  13. Professional Geology and Paleontology Language Codes.... There are TWO languages in the Sciences: (1) Professional Language (2) Amateur Language There are TWO major sources of Geological Information: (as far as this Topic is concerned) (1) Professional Journals and Books written by Specialists (books, papers, monographs, etc.) (2) Amateur books written in the layman's language (hobby, fossil books for the public) Often, and I probably should emphasize, OFTEN, the amateur collector of fossils or minerals will read a technical paper and not understand some or much of the terminology. There is no disgrace not understanding the terminology being used... but there is also NO EXCUSE not to deCODE the terminology to comprehend what has just been said. I was reading a bit on Cambrian trilobites and it was to prepare for some exploring some Cambrian trilobite locations. It applied to "blind trilobites" known as Agnostid Trilobites. Terms like oceanic-neritic boundaries, pelagic life, lithotypes, laminated strata, mimicry and other Scientific Code Words are used frequently. I am using "Code Words" for a lack of a more interesting term. Scientists can take one word that has a definite meaning. It would take several paragraphs or even a book to define the term... but they know what it means and use these "words". To an amateur, as myself, I must have a way to deCode the language. I have a book in mind that should be on every amateur's desk top, like a dictionary. Once YOU understand the definition of the terminology your understanding will benefit you for the rest of your life. Since most of the terminology has been in use for many years, the Second or Third Edition will provide enough information that is accurate. I see a Fourth Edition is available, but I would not spend the money for a copy, unless you are a Professional needing to use current terminology. A paper written in the past is what you most likely will be using and the terms will be defined in this book. Inliers or Outliers... very important stratigraphy terms in the UK that until I read the meanings... they meant very little to me at the time. Just simple things bring in large consequences. If you have already rolled your eyes back into their sockets... I understand. Many hobbyists have no use for a book to deCode Scientific language as they are not interested in getting into depth of the subject. There are 20% who are curious and want to understand. They are the most active on a Forum in identifying and explaining a subject in layman terminology. Want to find any crystal forms of Corundum? How about a fibrous silicate? Even mineral terminology needs some deCoding at times. Bates and Jackson Glossary of Geology "It is not really a mark of distinction for a geologist's writing to be so obscure that a glossary is required for its comprehension." Jules Braunstein "Definition is that which refines the pure essence of things from the circumstance." Milton "A leader who is lost during the hike, was lost before the hike began and needs no encouragement from those who persist in following, by sharing information lost in the translation."
