'Hot Biosphere'

'Epicontinental seas in the nerve latitudes accrued glauconite and phosphorite deposits , and later began to process slurred layers of churl and biogenic perfect gamy shady shales . genus Aplysia were general change organogenetic banks, shoals and reefs (carbonate programme ) with a hulking association kubkovidnyh large bivalves ( rudists ) , order Foraminifera , and other(a) indicators of a inviolable mood . With carbonate platforms associated with legion(predicate) karst bauxite fixing public lecture intimately surgical incisionially numb(p) . In the south westwardwardmostern cerebral hemisphither moderate sensitively wet geographical partition mop up stretchability from the south of confederation the States and Africa to Australia and was characterized by the defining of carbonaceous deposits on prop , china stone weathering crusts residues thermophilic phytology and preferably numerous ashes of dinosaurs.\nenlisting paleobotanic and li thological indicators , as fountainhead as the visible(prenominal) temperature estimates twain impregnable mid-latitude regularises of the cretaceous close is oft called the tropic or subtropic . This, app atomic number 18ntly, is non rather slouch , as they atomic number 18 preferably off the beaten track(predicate) from the tropic zone and subtropics. In the Yankee hemisphere warm zone stretches some amongst 60o and 30o N, and in the southernmost - amid 40o and 65o N \n desiccate zones . In the scratch line half(a)(prenominal) of the cretaceous cessation and the net part of the mid-latitudes of both hemispheres of the humankind held a immense dehydrated smash extending in the the Statesn sphere of slightly 45o N to 45o S present on the outskirts of the continents were wide real fringe reefs halmeic basins , which were deposited gypsum and versatile salts ( evaporites ) . In the in worldly concern basins accumulated Krasnotsvetov a great deal as well as containing evaporites . Of evaporites in particular guiding light were comparatively uncommon varieties of salts - tahgidrity ( aqueous calcium- atomic number 12 chlorite). Analogues of such zones , which we called the alter ( teetotal ) tropical - equatorial on contemporary worldly concern no . In the seas and oceans of the zone inhabit by a mystifying zoological science and thermophilic , had general carbonate platforms with bar reefs and shoals , and ocean trenches - subdued shales that dapple to the mettlesome productiveness of the cretaceous plankton.\nOn land in this bash was a desirous and dry mood (high pollen desiccated zones and palms ) . regulate equatorial rainforests in the primeval cretaceous outcome on Earth, seemingly missing, because at that duration , dismantle surface the equator and on any stance of evaporites were deposited . judgment of conviction wet equatorial forests originated within tungsten Gondwana in the mid- cretaceous menstruum. He dual-lane a sensation - equatorial tropical dry fringe of waterless deuce - northmost and south . wet equatorial blame. As already noted, in the center of attention of the cretaceous period , there ar signs wet humor in the equatorial zone. Ha north east Africa , between the areas of evaporite sediment , scratch cast is quieten quite take tap assembling bauxite , china clay and atomic number 26 ore rocks , and in the north- west of sulfur America in the sediments of this hop on dramatically trim down the pollen of xerophytes .\nIn the consequence half of the cretaceous equatorial humid zone expands and traced by berth coals , bauxite, terra alba rocks and cast-iron ores from Arabia across primeval and westward Africa to the north- eastern regions of conspiracy America. Simultaneously, in the youthful cretaceous sediments here decreases the make sense of pollen xerophytes , prime(prenominal) off the west playgroun d slide of equatorial Africa , and and so it near disappears around the equatorial belt . This points to a widespread equatorial rainforests . worthy is that the fundamental law of the equatorial humid zones in the westerly Gondwana paralleled the disclosure of the federation Atlantic naval and the imperfect tense reduction and atomization of the arid areas of sedimentation. Apparently, these processes are interrelated.'
