جبال لبومبو Lebombo Mountains، تُعهد أيضاً بإسم جبال لوبومبو Lubombo Mountains (بالپرتغالية: Montes Libombos)، هي سلسلة جبال ضيقة يبلغ طولها 800 كيلومتر في أفريقيا الجنوبية. وتمتد من هلوهلوى في كوازولو-ناتال في الجنوب إلى پوندا ماريا في محافظة لمپوپوفي جنوب أفريقيا في الشمال. أجزاء من سلسلة الجبال تقع في موزمبيق وإسواتيني.
الوصف
Geologically, the range is considered a monocline; part of a rifted volcanic margin. The Lebombo monocline was aligned with the Explora Escarpment off-shore Dronning Maud Land, Antarctica, before the break-up of Gondwana. The Lebombo monocline strikes N-S and dips to the east. It is composed of a sequence of Jurassic age volcanic rock, both basaltic lavas and rhyolitic flows and tuffs. The sequence rests on essentially horizontal Karoo Supergroup sedimentary rocks of the Kalahari Craton to the west and is overlain by Cretaceous to recent sediments to the east. The alternating resistant rhyolite and easily eroded basalts produce a series of parallel sharp cuesta ridges separated by savanna plains.
The range is relatively low with heights between 400 م (1,300 قدم) and less than 800 م (2,600 قدم). The highest peak is the 776 م-high (2,546 قدم) Mount Mananga. The 480 م-high (1,570 قدم) Longwe is the highest point in the Lebombo Range north of the Letaba River.
The mountains dominate Lubombo District in Eswatini. Towns in the area include Siteki in the centre, Lubhuku in the west and Mayaluka and Big Bend in the south with the Lusutfu River running past the southern region of the mountain range. At the north lie the towns of Simunye, Tambankulu and Namaacha, and the Mlawula Nature Reserve as well as the Mbuluzi River.
A number of rivers, including the Pongola, Mkuze, and Lusutfu, cross the mountains from west to east.
The name of the mountains is derived from the Zulu word ubombo meaning "big nose".
