Northern Rivers Geology Blog Update #1

I've been surprised about the success of this blog. I set out to put little facts that I knew about the geology of our region so that others who might be interested could pick these up. It has almost been a year of posting and in the last two days the blog had its 10 000th page view. Now, admittedly about 10% of the page views appear to be bots, but there is a greater than 90% chance that visitor number ten thousand was a person.

The most popular posts have been:
1. Why you wont find CSG here
2. Mythical Geology at the mouth of the Tweed River
3. The 'older' rhyolite in the north east
4. Mining and the Bible
5. Geology in the air

The biggest referrers have been:
1. Google
2. Wikipedia
3. Clarence Valley Today (blog)
4. New England Australia (blog)
5. Look and See New England (blog)

Thanks to all my followers for encouraging me with the blog. I hope that everyone continues to find something of interest here. I'll keep adding posts on about a weekly basis... I've got heaps of topics in mind so at this rate there should be another year (or two) worth of stuff before I start slowing down. Who would have thought how much geological diversity and how many natural features there are in the Northern Rivers.

Sorry to those of you from the highlands in the New England area and those from Coffs Harbour and further south, I've neglected the headwaters of the northern rivers and the southern areas but I'll look to fixing these oversights in the coming months. Feel free to leave your comments or ask questions if you wish.


  1. Rod your blog is so bloody interesting. I will never go to Kingscliff again and not think about a chamber of magma not too far below. I've had a few drives along the Mann river and I keep thinking about the theory that it flowed west.
    Okay I have a question. The Demon fault line in the Gibralter Range has long interested me. All of a sudden you go from Wet lush forest to dry heath and granite. I believe it is 100 miles long, when did it occur, why? What magnitude of earthquake would accompany such a dramatic rift?
    Keep up the posts

    1. Hi Mark,

      I've been meaning to talk about the Demon Fault this year. I'm so sorry I've not done a post on it. It is a remarkable feature and deserves lots of attention.

      The reason why I have not is because I need to subscribe to the journal 'Geology' put out by the Geological Society of America. I had a subscription last year but this year I saved some money and didn't get it. As academics say, it is hard to get past the research 'paywall'. 'Geology' has a particular article from the 1980's? which discusses some implications that I am not clear on... I don't want to post something completely wrong as my weakest area is structural geology.

    2. ask and you might receive - if you leave an email address to send it to.

    3. Thanks for your offer Anonymous. I'm hopefully resubscribing soon but have not had confirmation yet and therefore cannot log into the Geological Societies website. If you are able to provide me with an 'interim' copy of the paper in question I would be very grateful.

  2. When I started blogging I had no idea how to go about it or whether more than 5 people would ever see it! Your posts have great info in them and I'm sure that's how your readers find you.

    1. Hi Bettyl,

      Thanks for visiting and being so encouraging. I have now had a look at your photo blog. It is very good! I'm amazed by how good some of the photographers are who post on blogger. Your pictures are stunning, New Zealand is a wonderful place to live and visit.

  3. Rod, it is no surprise that you have had so many views on your blog pages.
    a) There are probably not many blogs that discuss a particular region like yours does.
    b) You do your research so you present the facts as you understand them.
    c) You write well.
    d) Your topics are of interest to non-geologists as well.
    So, congratulations on your success, and I look forward to reading many more of your fascinating entries.
    PS How much is a sub to the Geological Society of America? You have a birthday in a few months, don't you? ;-)

    1. Hi Wangiwriter.

      Thanks for the encouragement. You know my birthday... very close indeed! I'll let you know what is involved ;-)
