40 k.y. MILANKOVITCH-TYPE SEDIMENTARY rock shear cycles are accurate for AGE CALCULATIONS, within 20 k.y., compared to 100 k.y. ELLIPTICAL couplets

40 k.y. circular MILANKOVITCH-TYPE SEDIMENTARY rock shear cycles are accurate for AGE CALCULATIONS, within 20 k.y., compared to 100 k.y. ELLIPTICAL couplets- which allow binary basalt cones to be dated, both for the original extrusion and the later REJUVENATION CONE.
Adjacent to active laterally-moving features, such as the Hurricane fault, there occur a multiplicity of Milankovitch-type shear features in both sedimentary and igneous rock. These can be used to date the rock movements, and to calculate the AGES of vulcanism and fractures which allow streams to cut through hills and mountains- such as the Grand Canyon and the Virgin gorge. An introduction to this type of analysis and calculation is shown below, for a hill in Sand Mountain, Hurricane, UT:
This rock outcrop is circular, and of the 41 k. AXIAL CYCLE-type, due to rotation of the EARTH’S POLE in a wobble each 40 k. and 40 k. multiples with TIME, since the 2.15 M.Y. Eltanin asteroid strike. This bombardment left fragments from the Antarctica touchdown in sites in the Pacific Ocean, I have located this main strike by triangulation of shear circles left in the Southern Ocean, and it is covered by ice. This AXIAL rotation is the basis of measurement for sedimentary rocks, since it exhibits a diameter which extends 20 mm each year (20 km/m.y.) and the width E-W can be used to determine a 40 k.y. change of time westward. The smallest circular feature I have found is shown below, and is located on the Watchman trail in Zion NP. This is the remnant of the center of rotation of a circular feature (between 2 smaller ones), which is proven by the opposite side- which exhibits a vertical fault, filled by cement since the fault moving laterally cut through the center of the rotation. This requires some explanation, since I have independently found that some LATERAL THRUSTS shear laterally and create Coriolis rotation about the oppositely-moving sides (left-lateral faults create CCW, rising rotation and vice versa):

Notice that the lateral trace is about 45 degrees from the stratification layers, and has both vertical and horizontal components. The opposie side showed the slice through the rock excellently, but unfortunately my digital camera lost the frame, and I await the time when I can return for more work. Viewing the flat base, you can see a portion of the slice penetrating the sandstone.
Sand Mountain, from the Washington fault to the Hurricane fault has proven to be a treasure trove of fossil shear curvilinears, with the obvious circular traces left in a myriad of sizes. We will record these, starting with the view from Google earth along Hf:
THE LARGEST INVESTIGATED IS THAT SHOWN BY OBVIOUS SHEAR LINES TRACING ALMOST NE AT THE "ORV PLAYGROUND" JUST SOUTH OF SAND HOLLOW STATE PARK AND RESERVOIR. DON'T DRIVE THROUGH THE SAND ROADS WITHOUT 4WD, SINCE THE SAND WILL BOG THE AUTO. STOP INSIDE THE GATE- NO PARKING ALONG THE PAVED ROAD IS PERMISSIBLE.
THE OBVIOUS SHEAR FRACTURES AND TRACES IN THE SANDSTONE CAN BE VIEWED BY HIKING TO THE SOUTH ALONG THE CANYONS TO THE SOUTH AND EAST OF THE "SAND BLOWS" AS SHOWN IN THE ABOVE PHOTO.
I HAVE CONTINUED BY EXTRAPOLATION AND BY FOLLOWING THE TRACES OF SOME OF THE SHEAR CURVI-LINEARS, AND THEY EXTEND INTO AZ. USE THIS RULE TO DETERMINE TIME AND EXTENT OF ARCUATE FEATURES: THE RADIUS MAY BE FOUND BY DRAWING PERPENDICULR LINES FROM A PORTION OF A CIRULAR ARC. USUALLY YOU CAN FIND A QUARTER OF A MILANKOVITCH CYCLE, EVEN THOUGH IT IS ON-GOING (INCOMPLETE, ACTIVELY SHEARING NOW). MEASURE THE ANGLE BETWEEN TWO SUCCESSIVE RADII TO DETERMINE THE CIRCUMFERENCE OF THE CIRCLE. DIVIDING THIS CIRCUMFERENCE BY PI DETERMINES THE DIAMETER, WHICH SHOULD CHECK ROUGHLY WITH THE RADIUS FOUND PREVIOUSLY WITH THE ORTHOGONAL MEASUREMENTS.

ALONG Hf THERE ARE MANY ARCUATE FEATURES, INCLUDING SPIRALS AT Hf FAULT FACE, LARGE PLIOCENE ROTATIONS EXTENDING INTO AZ (ABOVE CASE), AND MANY MORE THAT MILANKOVITCH HAD NOT USED FOR CLIMATE AND WEATHER CALIBRATIONS (SUCH AS THE ICE AGE CORRELATIONS EACH 100 K.Y.). BELOW IS A GOOGLE EARTH PHOTO SHOWING SEVERAL OF THE CYCLES- SMALLER THAN MILANKOVITCH INCORPORATED. I HAVE FOUND THAT THERE ARE MANY WOBBLES OF THE EARTH, FROM THE INFLUENCE OF THE MOON, PLANETS- SUCH AS JUPITER, SATURN, URANUS, AND NEPTUNE- AND THE SUN. I AM SLOWLY INCORPORATING AS MANY OF THESE AS SAND MOUNTAIN AND THE HURRICANE FAULT HAVE PRESERVED IN THE ROCKS (AS CIRCULAR FEATURES OF VARIOUS DIAMETERS). SIZE OF THE CIRCLES IS INDICATIVE OF THE TIME OF THE WOBBLE IN YEARS, WHEREAS THE AGE HAS BEEN FOUND TO BE RELIABLY CALCULATED BY THE DIAMETER/20 KM/M.Y. e.g. 20 KM DIAMETER IS FOUND FOR 1 M.Y. MOVEMENTS- SUCH AS WITH THE DISTANCE BETWEEN Hf AND THE WASHINGTON FAULT:
You can view and analyze one of these MILANKOVITCH ELLIPTICAL CYCLES of 100 k.y. duration, by using Google earth distance tool and searching for circular patterns in the drainage of streams and arroyos. Drainage finds the factured rock, which has been sheared by the rotation of porions of the EARTH'S CRUST. NOTE THE ELLIPTICAL ARC SURROUNDING A VOLCANIC EXTRUSION NEAR THE GRAND CANYON. THE ELLIPSE CONTAINS MANY SMALLER AXIAL, PRECESSIONAL, AND SMALLER CIRCULAR PATTERNS DUE TO THE WOBBLES OF ThE EARTH:
