Columbia SuperContinent

 Columbia was a supercontinent thought to have existed about 2,500 to 1,500 million years ago in the Paleoproterozoic Era. It is also known as Nuna and Hudsonland. It consisted of proto-cratons known as the Amazonian Shield, Australia, Baltica, Laurentia, and the Ukrainian Shield. It may have possibly included Kalaharia, North China and Siberia as well.

Following its creation by combining most or all of the known bits and pieces of land, Columbia continued to grow by various areas of volcanic activity that created magma flows.

Columbia began to fragment about 1.5 to 1.35 billion years ago.

This is pretty much the sum total of what I learned from this article. I find it irritating when an article that is supposedly written for the average person presumes that the average person has taken a course or three in the specific subject covered by the article, and so it is filled with language and terms that actually mean very little to the average person. More and better pictures might have helped.

There was one graph that seemed to say that when Columbia began collecting its various pieces, single-cell life was strong, as was photosynthesis. Then a type of life known as eukaryotes began. This is a very broad type of life, where the cell nucleus containing the cell’s DNA is enclosed within a nuclear envelope. This is so broad a definition that these days, it includes all life except some or all types of bacteria.

At the very end of Columbia’s life, as it was beginning to break up, multi-cellular life was just beginning.

I don’t think I’d want to try to colonize a planet during this period of its life. I don’t think you could get crops to grow unless you brought along various soil denizens that would help make the soil and its potential nutrients usable by your plants. But then, I don’t have a degree in biology or agriculture, either, so maybe I’m way off base there.

I’d like to take a course in paleogeology, I just don’t know where I’d have to go to find one.

An Update on MoonPhaze Authors

 Okay, I don’t do this very often, so I hope you’ll bear with me. Things have been busy here, and I thought I would let you sneak a peek into the lives of a pair of authors.

In August, I saw a call for submissions to a themed anthology, with a 30-day deadline. I told my husband, who writes science fiction. I knew he was busy with some of  his hobbies, but I wanted to give him the chance to participate. The first thing I sold was a story to a themed anthology, so I have a bit of a soft spot in my heart for them.

Meanwhile, I tried to think up a plot for a suitable story. It only took me a couple days to realize I had 2 plots! So I wrote both of them. When I asked if they would accept multiple submissions, they said yes, so a few days before the deadline, I sent both of them in.

We are not sitting around, chewing our fingernails and climbing the walls waiting for word on whether or not we were accepted. The contributors do not, generally, make a lot of money from anthologies, but it’s nice to be able to put them on our ‘resume’, so to speak. And yes, we are competing with each other, but I am also competing with myself!

In other news, I recently took an on-line class on how to effectively use Goodreads to let people know about our books. So I have spent some time getting my husband’s books listed on Goodreads, including 2 that have not been published yet, but have been edited and are waiting for the cover to be done. I never imagined how much marketing in involved before the book is published! I had to make an entire new ‘To Do’ list for the Goodreads site, to keep me on track.

I also spent some time this week trying to upload the files for his next book, “De-Evolution” to our printer. They changed the way files are uploaded, so I had to re-learn the entire procedure again. And I’m not done, because somehow I managed to come up with 2 chapter titles for each chapter, so I’m exchanging emails with their support crew, trying to figure out how to eliminate one set of chapter titles, preferably the ones they added.

I should also upload the file for the e-book, but I figure, one problem at a time.

Upcoming books by John Lars Shoberg include “De-Evolution”, with a tentative release date of November 15, 2020 and “The Stone Ship”, with a tentative release date of May 15, 2021, and which is a sequel to his first book (The Stone Builders). Both of these books are currently having the covers done. I have a book, “Hank’s Widow”, tentatively scheduled for release on July 15, 2021. Actually, the author name will be Linda (NMI) Joy, which is my pen name for romances.

And there you have it. In among all the other things in our lives, I have accomplished this in the last couple of weeks, with other on-line seminars on Sunday and next Tuesday. In the meantime, it’s time to start editing yet another of John’s books, “And the Meek Shall Inherit”.

I need clocks that run slower.
