Lake-Cuitzeo: Dual-Impact Stratigraphy; Cueva da Pedra-Pintada: Dual-Comet Celestial-Cartography.
Brazilian Pedra-Pintada site´s lowest stratum provided 14C and luminescence dates for End-Pleistocene, pre-pottery, Paleoindian middens, with soft sand, charcoal and red pigment layer. That same pigment, chemically identified, was used in cave-wall pictograms above, providing stratigraphic dating (Roosevelt,1996; Michab,1998). These pictograms, in celestial-paleo-cartography, depict two comets (Bujatti-Narbeshuber,1997a).
That lowest, dated, Pedra-Pintada stratigraphic-layer of 30 cm, associated with two comet-pictograms, is most tellingly followed by culturally sterile 30 cm soil, again finally followed by Holocene-middens (65 cm) of thriving pottery-age populations.
The anthropomorphic pictograms encode the concentric comet-nucleus-coma-halo threefold structure as descending head identically consisting of three concentric layers, only one with radiant hair. Dual comet-dust and plasma-tail is encoded as parallel legs extending upwards. Two different comet-stages and two different comet-trajectories are evident: one with concentric comet-head, radiant hair, descending, the other comet-head, without hair, not radiating, burnt out, as concentric impact-crater “fallen-dead”, with parallel legs, tied together, also forming “H”= ”fallen-dead”-symbol.
Magdalenian Impact Sequelae Symbolizations (MISS) by AO-KISS-impact-survivors in Göbelli-Tepe use “H” on T-pillars 43 and 18. The “SNAKES-((H-I-T))-SPOT” decoding formula means: (Prof.Klaus) Schmidt-Never-Assumed-KISS-Equates-Snakes (= Taurid impactors), that “H”= “Hurt” the “I”= “Intact-upright-alive”C “T”-pillar. “Hurt-fallen-dead” symbolization by “I”-column=T-pillar-symbol of ritual-centers-Mid-Atlantic-Plateau-MAP-Civilization, cartographic 90° (“I”=West-up to North-up=”H” ) Solar-Polar-Orientation-Transition, within two-step Mega-tsunami = ((double-brackets)). This abstract-composite-proto-writing symbolizes AO-KISS induced two-step Mid Atlantic Ridge & Plateau Lowering Events (MARPLES) within T-pillar-43-celestial-paleo-cartography (Bujatti-Narbeshuber,2022), precession dated 12.850-13.000 cal BP (Sweatman,2017, 2022).
Pedra-Pintada, dual-comet, pictogram-stratigraphy 14C dated 11.145 + - 135, calibrated to 13.300- 12.750 cal BP (95% confidence level) has mean calibrated age 13,010 cal BP. This fits AO-KISS-Bipolar-Sulfate-Impact-Volcanism-Heptaplet-proxi Laacher-See-Tephra isochrone of 13,006 + - 9 cal BP (Bujatti-Narbeshuber,1997a,Reinig,2021). It also fits earliest Mayan Codex Troano calendar date 13,124 cal BP and maximally 274 years later Continental-Ice (CI)-Carolina-Bays-KISS date 12.850 cal BP.
Dual CI-AO-KISS-MARPLES fit Mexican-Lake-Cuitzeo (MLC) stratigraphy consisting of three-layered-lacustrine “Black-White-Graphite-Mats”.
There 14C-“Dead-Old-Graphite” (DOG-)-Mats” mark P/H-boundary-AO-KISS-MARPLES with Impact-Catastrophic-Climate-Transition (ICCT):
MLC-stratigraphy-level below (2,55 m) confirms by “Black-Mats” from high humidity algal organic carbon, identity with North American “Black-Mats”, following from Continental-Ice-KISS with secondary meteoritic-ice-ejecta-impacts, shaping 500.000 mathematical ellipses, Carolina-Bays, into earlier AO-KISS-“White Mats” (Muck,1976;Davias,2007;Zamora,2015;Bujatti-Narbeshuber,2023).
MLC-stratigraphy-level above (2,70 m) confirms by “White-Mats” identity with North American precursor of Carolina-Bay-formation as bleached-sand A2-horizon, non-fossiliferous-sand Goldsboro-Ridge-Enigma, nearly pure silicate, industrial white glass-production-grade-sand (Daniels&Gamble,1969,1970,1972), K/Pg-like (Senel,2023), European Usselo Horizon (Andronikov,2016), all documenting aeolian-transport by AO-KISS-MARPLES-Megaplume of ocean-floor-magmatic-volcanic-clastic-material in meso-stratospheric Mega-Hunga-Tonga-(2022)-like steam-plume, raining down in torrential-acidic-bleaching waterfalls (Bujatti-Narbeshuber,2022,2023).
MLC-lowest-stratigraphy-level with Nano-Diamond-peak (2,75-2,8 m) as 14C-depleted “DOG-Mats". Disturbing MLC-core 14C dating, below “White Mat” (2,75 m), a 1 cm thick layer, that ”contains thin millimeter-sized-interbeds of black organic carbon…without form or structure” of almost pure elemental carbon, enigmatic, not “plant-derived kerogenous organic-matter”. “Currently, the source of this old carbon remains unclear” (Israde-Alcántara,2012).
Ocean-floor Black-Smokers, producing graphite with very old 14C-ages (Estes, Nature Communications, 2019), should fully account for “DOG-Mats” through AO-KISS-MARPLES-Megaplume aeolian-transport around Azores-Triple-Junction.
