Online Guidebooks to Canadian Fossils and Geology
Online Guidebooks to Canadian Fossils and Geology
Hi,
Recently, I came across a couple of field trip guidebooks
about fossils and geology of areas within Quebec and
Ontario,Canada. The first guidebook is:
Hofmann, H. J., and and M. D. Chartier, 2006, Canadian
Paleontology Conference Field Trip Guidebook No. 11
Canadian Paleontology Conference, Redpath Museum,
McGill University, Montreal (QC) October 13–16, 2006
It contains Field Trip A - "Stratigraphy of the Montreal area"
by H.J. Hofmann and Field Trip B - "Fossils of the Champlain
Sea." the Redpath Museum, and the Saint-Nicolas site by
M. D. Chartier and M.E. Cournoyer
It is at
http://www.academia.edu/2780812/Canadian_Paleontology_Conference_Field_Trip_Guidebook_No._11
and citation at http://www.gac.ca/publications/view_pub.php?id=188
The second guidebook is:
Frank R. Brunton, Elizabeth Turner and Derek Armstrong,
2009, A Guide to the Paleozoic Geology and Fossils of
Manitoulin Island and northern Bruce Peninsula, Ontario,
Canada. Canadian Paleontology Conference Field Trip
Guidebook No. 14, 76 pp., SBN 978-1-897095-45-4
It is
at:https://www.academia.edu/7132983/A_Guide_to_the_Paleozoic_Geology_and_Fossils_of_Manitoulin_Island_and_northern_Bruce_Peninsula_Ontario_Canada
I found them in Google Advanced Search using
"guidebook geology site:https://www.academia.edu/”
Also, using in Google Search: "Friends of Pleistocene guidebook
site:https://www.academia.edu/" yields some interesting results.
Finally there is “Hunting for Whales in Eastern Ontario,” Fossils

Online Meteorite Lectures
Online Meteorite Lectures
Incoming: Learning to love the meteorite
Geological Society of London lecture
Lecture by Dr Ted Nield given at the Geological Society
on 19 December 2012 as part of the 2012 Shell London
Lecture series.
https://www.youtube.com/watch?v=SuYKYRHMq4U
"New research is suggesting that 470 million years ago, a
stupendous collision in the Asteroid Belt (whose debris is
still falling, to this very day) bombarded the Earth with
meteorites of all sizes. A revolutionary idea is emerging
that the resulting ecological disturbance may have been
responsible not only for massive worldwide submarine
landslides, but for the single greatest increase in biological
diversity since the origin of complex life -- the hitherto
unexplained Great Ordovician Biodiversity Event."
Lecture 2
Geology in Space: Meteorites and Cosmic Dust
Geological Society of London
Published on Aug 7, 2014
By Matt Genge, a planetary scientist and geologist
from Imperial College London
https://www.youtube.com/watch?v=OMTl5fY4QW4
"Geology no longer is the study of the Earth. Rocks
are found throughout the universe on other planets,
asteroids and comets and as debris ranging in size
down to the tiniest pieces of stardust."
Lecture 3
The meaning of meteorites
Royal Astronomical Society Lecture
Published on March 24, 2015
by Dr Ted Nield, Geoscientist Magazine
Royal Astronomical Society public lecture, 10 February 2015
https://www.youtube.com/watch?v=6lgd_bJELtM
"Ted Nield surveys the ways impacts have influenced life
on Earth, and suggests that, as with ideas, meteorites have
'timeliness', because the effect of any single cause, in
human as in Earth history, is controlled largely by the
context in which it occurs."
The below lecture has nothing to do with meteorites.
It is just fun fossil hunting.
Fossils and Mud: A Jurassic Adventure
Geological Society of London, London, Lecture June 2015
by Neville Hollingworth,University of Birmingham
https://www.youtube.com/watch?v=-0pj8MUicSA
"Having spent over 25 years wallowing around in mud,
Neville Hollingworth will introduce you to some of the
finer aspects of the Middle Jurassic of North Wiltshire
and South Gloucestershire. …
This lecture will be a pictorial tour of some quite unusual
sites, digging techniques, notable characters and chance
discoveries that made the national news."

meteorites of all sizes. A revolutionary idea is emerging
that the resulting ecological disturbance may have been
responsible not only for massive worldwide submarine
landslides, but for the single greatest increase in biological
diversity since the origin of complex life -- the hitherto
unexplained Great Ordovician Biodiversity Event."
Lecture 2
Geology in Space: Meteorites and Cosmic Dust
Geological Society of London
Published on Aug 7, 2014
By Matt Genge, a planetary scientist and geologist
from Imperial College London
https://www.youtube.com/watch?v=OMTl5fY4QW4
"Geology no longer is the study of the Earth. Rocks
are found throughout the universe on other planets,
asteroids and comets and as debris ranging in size
down to the tiniest pieces of stardust."
Lecture 3
The meaning of meteorites
Royal Astronomical Society Lecture
Published on March 24, 2015
by Dr Ted Nield, Geoscientist Magazine
Royal Astronomical Society public lecture, 10 February 2015
https://www.youtube.com/watch?v=6lgd_bJELtM
"Ted Nield surveys the ways impacts have influenced life
on Earth, and suggests that, as with ideas, meteorites have
'timeliness', because the effect of any single cause, in
human as in Earth history, is controlled largely by the
context in which it occurs."
The below lecture has nothing to do with meteorites.
It is just fun fossil hunting.
Fossils and Mud: A Jurassic Adventure
Geological Society of London, London, Lecture June 2015
by Neville Hollingworth,University of Birmingham
https://www.youtube.com/watch?v=-0pj8MUicSA
"Having spent over 25 years wallowing around in mud,
Neville Hollingworth will introduce you to some of the
finer aspects of the Middle Jurassic of North Wiltshire
and South Gloucestershire. …
This lecture will be a pictorial tour of some quite unusual
sites, digging techniques, notable characters and chance
discoveries that made the national news."

Great YouTube Lecture Series On Engineering Geology
Great YouTube Lecture Series On Engineering Geology
There are some great Youtube lectures about engineering
geology by Dr. David Rogers, University Missouri at
https://www.youtube.com/channel/UC8rEEIEMhazZBvsKB_e7xzg .
Although long, the nice thing about these lectures is
that person can view them at their own pace and time.
Also, Dr. Rogers occasionally talks about how to survive
as an consulting engineering geologist and the trials and
tribulations of field work during his lectures.
Another web page contains links to the Powerpoint files of
the lectures at
http://web.mst.edu/~rogersda/umrcourses/ge341/ .
For example, are some very nice examples of spheroidal
weathering and jointing in the powerpoint at
http://web.mst.edu/~rogersda/umrcourses/ge341/online_lectures/weathering/Weathering-pt4.ppt
.
