is Pleisticene - even today minor tectonic shifts alter water course directions in the Savuti Channel. Seehttp://www.bgr.bund.de/EN/Themen/Wasser/Projekte/abgeschlossen/F+E/Senken_Botswana/se nkenbotswana_projektbeschr_en.htmlStevns Klint
- as it records the exact boundary between 2 periods (Cretacious-Paleocene) we have to decide which to choose. I would suggest Paleocene on the "logic" that the boundary wasn't there until the latter started!Qapac Nan
Nom file quote "The central thrust of the Incas' policy, initiated in the sixth century and recorded in millennia of pre-Hispanic Andean history, was expressed to the fullest in terms of territorial spread and maximum linkages among cultures in the fifteenth century"
So this latter century seems the best?Silk Roads
The phrase used again and again in the Nomination file's overall description is "the initial section of the entire Silk Roads used from the 2nd century BC till the 16th century AD"
and "Having witnessed significant stages in the development of human civilization on the Eurasian continent over a period of eighteen centuries between
the 2nd century BC and 16th century AD,"
etc etc. I can find no reason not to use the first date rather than choosing a date from within the period.Trang An
. Despite the fact that it includes Hoa Lu - the former capital between 968- 1010 CE absolutely NO mention is made off this place in the Criteria or OUV!! Instead these relate to the natural and cultural aspects surrounding the changes to the Karst lansdcape over a much longer period
a. "Trang An is an outstanding locale within the Southeast Asia region and in the wider world for demonstrating the way that humans interacted with the natural landscape and adapted to major changes in environment over a time period spanning more than 30,000 years, between about 1,200 BP and 33,100 BP. The remarkably long and continuous cultural history is revealed as being strongly associated with recent geological evolution of the Trang An limestone karst massif. Early humans have been an integral part of the biotic communities that have become established in the massif environs since at least the Last Glacial Maximum. During this time they endured some of the most turbulent climatic and geographic changes in Earth history, including repeated submergence of the landscape due to oscillating sea levels (Crit v)
b. "The story of karst evolution, so well told at Trang An, is of even greater scientific significance because of evidence that sea level has varied here in the past. During the Pleistocene and Holocene, the margins of the Trang An massif were invaded and re-worked by the sea many times. Trang An is widely regarded as being of global importance for illustrating the interaction of karst evolution with changing sea levels and associated water-table levels." (Crit viii)
c "Trang An is, therefore, an outstanding in situ archive of changing environmental conditions and people's responses to that change extending into the deep past." (from OUV
So it has to be Late Pleistocene or Holocene?? Late Pleistocene finished c 17k years ago -about the middle of the period covered in Crit v so no help there!! I would probably choose Late Pleistocene on the basis that it was the first major period involved??Hamiguitan
. "Past geological processes that took place in this region transformed the local geography into a semi-isolation that is the Pujada Peninsula, the cradle of the Hamiguitan Mountain Range"
(detail under Crit X)
The peninsula dates to Cretaceous - "The Mt. Hamiguitan Range is part of the Pujada Peninsula, deduced as a product of magmatic and tectonic actions generated by the subduction of the Philippine Sea Plate. The tectonic collision caused the oceanic crust to rise up, creating the mountain range. The melting of the subducted slabs as it sank into the subduction zone generated the Cretaceous volcanic rocks of the Pujada Peninsula
" (Nom File).
But to what period does the flora and fauna for which it was nominated belong ? ("MHRWS represents a complete set of relatively intact mountain ecosystems in this significant biogeographic region of the Philippines.
"). I haven't been able to discover anything further.
