Structure Measurement for Geologists

[@darrenstanleysmith5207]

"poisons your data if you put crap measurements in there". Cheers Nick. Words to live by!

Dont mince your data or your words!

Очень интересно! Спасибо. Учу специальную геологическую лексику по Вашим видео!❤

[@GeologyUpSkill]

Большое спасибо. KZbin планирует выпустить озвучку на других языках, но пока этого нет.

Love the knocking stick. What do you think of it? Any starting g points for a supplier? I've been looking for an 800 gm cross panel with out luck. Blacksmiths used them.

[@GeologyUpSkill]

Thanks Geoff. It's a Stinger from Trow & Holden. A stone masonry hammer. I have been working with them to design a new tungsten tipped hammer for geologists.

Thank you ✊

Thanks for taking time to comment.

My Garmin GPS from 20 years back, I still have. The way it works is it gets you within 60ft, and then the satellites drift your position around, apparently in a circle. You don't ever get an exact spot. Now, surveyors have accurate GPS, and maybe there is a licensing problem or as I have been told, the randomization is built in so you cannot use it for a weapon. The public in the US gets stupid GPS.

[@GeologyUpSkill]

Most consumer level GPS and phones now get to within about 15 feet if there is a clear view of the sky.

[@donaldkasper8346]

@@GeologyUpSkill If may be within 15 feet but the location also drifts around. It can get you to the hillside you want.

It won't take long till you have tens of thousands of subscribers

[@GeologyUpSkill]

That would be great, but I don't think there are enough geologists in the world...

[@keithaugust9303]

Thank you so much for these clear, concise techniques!

[@GeologyUpSkill]

Thanks. Hope you find the info useful. There are lots of ways to collect the data, but consistency is very important, particularly when working as part of a team collecting data in the same area.

[@nils6097]

What GPS system are you using, especially for recording your strike and dip measurements?

[@GeologyUpSkill]

The hand unit is a Trimble Nomad. It has a built in GPS. I am running Discover Mobile software to collect the data for structure and all other mapping and sampling. It's an old system now, but still getting the job done.

[@johnmenzies6865]

Dip and dip direction.....why would you do anything else?

[@GeologyUpSkill]

Precisely!

[@vispolatov]

Traditional brunton is better designed for strike and dip. North American right hand rule is considered acceptable

[@galatura]

I have a sighting compass, to be honest this is wholly new use for them from my point of view.

[@GeologyUpSkill]

Great. If you learned something useful, my work is done!

[@galatura]

@@GeologyUpSkill I certainly did !

[@emmanuelhuku5062]

Find it very helpful

[@GeologyUpSkill]

Great. That's why I make them!

[@vernshein5430]

Only geologists could have two Right Hand Rules each of which is the opposite of the other :-)....... One advantage of using a Brunton pocket transit or similar is that it's easy to see the true dip as it is perpendicular to the strike you just shot using the bullseye bubble level to get true strike. You also can use it for shaving........ That being said I see the value and efficiency of dip direction. Pre GPS I ran my traverses with a Silva 15 TDCL mirror compass for the azimuths between stations, measured the slope angle for distance corrections with a Suunto clinometer (always know your eye level on each of your field assistants) and did structural measurements with the Brunton. Nowadays the first two have gone the way of the dodo with GPS. The one exception to mapping structure in creeks was at Mt. Kare where there was a 2000-4000 person gold rush and ZERO outhouses. When mapping the creeks, which were often used as latrines, I became very adept at taking structural measurements without getting close to the outcrop and I learned to map quickly............

[@GeologyUpSkill]

Yes. GPS changed everything the day they switched off Selective Availability and accuracy went from 100m to 10m.

Hello

[@nibiruresearch]

I know of a missing link in the education of geologists. When we look at the many horizontal layers that we find throughout our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata of India and the Popol Vuh of the Mayans and others. They tell us about a cycle of seven disasters that separate the eras from the world. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and meteorites. They also create a cycle of civilizations. To learn much more about the recurring flood cycle and its chronology, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

Testing of theories like that is precisely what geologists do. The evidence is in the rocks. If you are keen to find the real answers for yourself, then I recommend that you study geology!

[@nibiruresearch]

@@GeologyUpSkill If you don't start with the catastrophe theory and seriously start thinking of a possible cause for this event, you are walking in the dark. An American colleague reached the conclusion that a heavenly body must be the cause of the cycle of catastrophes already in 1883.

[@GeologyUpSkill]

@@nibiruresearch Sciences is the process of evaluating all theories to assess which one best fits the evidence at hand. If you start with the assumption that one theory is correct, you are likey to ignore evidence that does not support it. That is poor quality science and poor quality geology.

[@nibiruresearch]

@@GeologyUpSkill I am a researcher, not a scientist, so I don't have to follow your rules. By reading and analyzing ancient information that is denied or neglected by scientists, I found a red line that is connecting many events worldwide.

[@GeologyUpSkill]

@@nibiruresearch A good scientist does not deny or neglect any information. The heart of the scientific method is to assess all theories against all available evidence and then decide which theory is most likely to be correct.
