mare lava 中文意思是什麼
mare lava
解釋
月海熔巖-
Scientists do not think the mare basalts in the basins are the source of the gravity anomalies ; individual lava flows appear to be quite thin ? from a few meters to a few tens of meters ? and total accumulations are typically 200 meters or less
科學家不認為盆地中的月海玄武巖是這些重力異常的來源,因為個別的巖漿流似乎相當薄(從數公尺到數十公尺) ,且累積總計通常少於200公尺。 -
The spa basin as a whole is largely unfilled by mare lavas, whereas even the smallest basin on the near side tends to have copious lava fill
整體而言,大部份的spa盆地沒有被月海巖漿填滿,即使是近地面最小的盆地也被大量的巖漿所填充。 -
Because these mare lavas predate the highland debris layers, which were laid down during basin formation 3. 8 billion years ago, they indicate that the eruption of lava onto the moon began well before the ages of the oldest mare flows sampled by apollo
因為這些月海巖漿,比38億年前盆地形成時產生的高地遺屑年代久遠,它們顯示月球上巖漿開始噴發的時間,遠早於阿波羅所採集樣本中最古老的月海巖流。
