The vestiges of human activity in stone era in Dong Nai

 6 Monuments of Hamlet Lo Hang Gon Coal , communal dispensation ( after the Xuan Tan ) , Xuan Loc is located 7 km south from Mount Cam Injection and 3.5 km north of the E. Saurin discovered in the years 1966 - 1968 and full disclosure in 1971 under various different names ( Hill 275 , Coal Fireplace , 's Gia Nghia , Friday holidays) . By Mr tool found in soil 40 cm deep red turtleneck steps of 35-40 cm compared with LET streams , including hand axes 3 (with the hand ax is considered typical A Son ) , 5 tool crude has 3 sides (with the trait Abbeville - a Son ) , 3 multi-faceted tool , shaped tool axes 1 , 1 easel spearhead , 1 scraper and throw some stones . Based on the type of artifacts and landforms , E. Saurin ratings Gon 6 A Son in early stages , after 65 thousand years ago , corresponding to steps 40-50 m of the Mekong River in Southeast Cambodia , across the Mindel glacial period ice time or early Mindel - Riss in Europe . According to some researchers , the discovery of E. Saurin and 4 -piece collection of stripped revenues more years from 1977 to 1978 at Hang Gon 6 , along with relics of that mountain , the area has expanded development of " hand ax culture " or " cultural tool has 2 sides " existed in Europe , Africa , Asia Minor , India in the east . On the other hand , Hang Gon 6 specification with stone crafted Clacton - Levallois and almond-shaped hand ax like tool of group Palaeothic apes living in Patjitan ( Indonesia ) and with the mark "culture nodes pebbles "that popular in Southeast Asia , could be dating A - Son soon ( or Ableville ) - A - Son late , around 60 thousand years ago .

     At Dau Giay Highway 2 along the 1 , located in 2 districts bordering Thong Nhat- Xuan Loc ( Long Khanh district today ) , E. Saurin was found in 1968 4 relics steep coastal streams , lower surface area of about 15m , including : 1 almond-shaped hand axes , scrapers 2 , 1 carry key specification A Son late .

     Since 1975, Dong Nai Museum and Archaeology Center ( KCH ) - KCH Institute , Geological Group 500 organizations have repeatedly survey the area and discovered many tools at Mountain Land ( 1 public Duke particular piece , 1 tool shaped ax , 1 hand tools 2 type A Son soon ) , Cam injection ( 3 nodes like ice dam scraping or cutting tool ) , excoriation (James Liao ) ( 1 tight crude tool nose pointed , 1 duke piece , 1 claw fossil animals ) , Binh Loc ( 1 almonds tools like hand axes A Son ) , Binh Xuan 2 ( 1 corresponding tool almonds A Son later time ) of the Xuan Loc - Long Khanh and Doc Mo ( Gia Tan 2 ) ( 1 bubonic rock like four hands , one hand ax shown almond characteristics A Son of the Middle period late Mindel interglacial - Riss about 30-25 thousand years ) in the Mini Nhat Phu Quy same ( Figure 1 tool forks , 1 piece outsourcing can deprive the A Son of late ) in Tan Phu and Ba Rach Gia ( 3 flaking tools with a typical 1 tool axes A picture paints later in the Eternal ) .

     Overall, these characteristics are the domain of the red soil hilly terrain Basalt , volcano area has many ancient , uneven surface ( height 150-200 m ) , with many volcanic peaks near the oval mouth was remnants and traces of lava flows ( thickness 8-15 m ) long alternating running multiple streams cut and deep erosion gullies ( 10-15 m ) . Based on tectit dating , the age of the basalt geology in Xuan Loc approximately 64 thousand years ago . All tools in Xuan Loc picked up on the surface are lava , which are identified early age A Son ( Hang Gon 6 , Mountain Land , Doc Mo , Suoi Da ) to late ( 2 Dau , Binh Loc , 2 Xuan Binh , Cam injection , Phu Quy ) , corresponding to the Mindel interglacial period - the first to break the ice Riss Riss - Wurm in Europe , with many dating generally admitted from 60 thousand to 25 thousand years from today . In these locations , the scientists collected 35 carries flaking tool mark processing techniques and primitive type , not some rock thrown with an average diameter of 8-10 cm at Hang Gon 6 and some nuts like rock " four hands " in open reading . They are made from basalt rock - popular form of raw materials in the region , with many characteristics of primary fissure hard but brittle and fashioned into tools . On the type , they include hand axes 7 ​​, 4 threefold tool , multi-faceted tool 3 , 4 curettage , 3 -pronged , 1 image plate engine , 6 -piece Duke , 3 nodes rocks , mostly collected in Goods Gon 6 ( 18 specimens ) , Dau 2 ( 4 specimens ) and Nui Dat ( 3 specimens ) . The remaining locations only 1-2 template .

     Although not recorded in the stratigraphic archeology and culture not seen attached to the ancient ruins Profile - paleontology respectively , Xuan Loc many specimens , especially hand ax and ax tool, many scientists Vietnam and experienced foreign study acknowledged the true product of human hands reaching out to ancient hill settlements on domain sales Basalt red soil plains of southeastern Dong Nai and Ministry , almost simultaneously with the group Lang Son ape-man with relics including ( 10 molars , canines people with some morphological characteristics that Homo Sapiens advances nearly the same Peking teeth , bones and fossilized bamboo bear , elephant tooth check , Orang orang dwarf , giant apes , tigers, leopards star , wild boar , monkeys , porcupines ) settlements in the limestone caves Recommendations Assessment , Evaluation Hai - Binh Gia highlands and the northern Thanh Hoa apes delta plain falls three rivers Code - Chu river . Life of the apes have many tens of thousands of years in the jungle primeval and the steps Dong Nai red lava land may have been the life of the " herd Homo erectus " ( Homo erectus ) is quite developed ( Ha Van Tan 1977) . It is a wild life but primitive life forms is the time of a social renewal , said making hand axes and tools axes to form tight beat , scraping and cutting tool for stripping terms piece or key and stone throwing routine use in hunting and gathering . Maybe it is also a known human society to set up tents nestled through tropical rain forest , has known the magic of the creative types - fire cooked food , luminescent jungle and chase animals data around the primitive huts . Usage begins the process of conquering the Dong Nai noted the traditional tools crafted from Basalt boulders that the first activities of the society , Xuan Loc and traditions I have manipulated their pebbles to maintained in the ancient society of Dong Nai many thousands of years later , with the first traces of the history of this important period in the entire highlands and eastern coastal delta of southern Vietnam is gradually authentication through the collection like tools Son Vi ( Hill Country Report - Hue 's plains - Quang Tri , the Ta Lieng - Lam Dong , wood Finally - Dong Nai ) , the tool -marked flaking technique plasticizer Rating ( paragraphs - in Dak Lak , Bau Du - Quang Nam , Bau Hoa - Binh Thuan , Hill Ma - Lam Dong ) , tool sharpening blade type Bac Son ( Ndut Lieng Krak - Dak Lak , Binh Long - Binh Phuoc ) , Video Duke piece tool set and pebble processing Hang Gon 7B2 and relics marked Peace - Bac Son recorded in sites - the early burials Stream Iron Weasel . The new evidence recorded activity of primitive man to the old post- Neolithic Stone in Dak Lak , Lam Dong , Binh Phuoc and Dong Nai can be considered as the first traces of the most complex and far Dispatch chemicals - industrial processing nodes according to the traditional pebble Son Vi - Hoa Binh - Bac Son - Bac Son post south of Vietnam .
