正长花岗岩主要矿物成分是肉红色正长石、白色石英、黑色黑云母。花岗岩英文名称granite，源自拉丁文granum，意指颗粒，granite即指组成花岗岩的矿物是颗粒状。岩石矿物粒径不同就有不同的岩石名称。矿物粒径5～10mm的花岗岩叫粗粒花岗岩，0.3～3mm的叫细粒花岗岩。此处细粒正长花岗岩呈脉状侵入早期的粗粒正长花岗岩。
Fine-Grain Syenogranite
The main minerals of syenogranite are flesh pink orthoclase, white quartz and black biotite. The name granite stems from Latin granum meaning grain. Granite means that it is comprised of granular minerals. Rock minerals with different grain sizes result in different rock names. The granite of 5～10mm mineral grain sizes is called as coarse-grain granite, 0.3～3mm one called as fine-grain granite. Here, the fine-grain syenogranite in rock vein invaded into early coarse-grain syenogranite
风化壳是地表上不连续的原岩原地的残积物堆积层。上是土状碎屑，往下碎屑颗粒增加，粒度变大，再往下为岩石碎块至完整岩石，这是风化壳剖面分层。风化壳是地表岩石经水、气、生物等物理、化学作用（风化作用）后残留形成。原岩中易风化、易流失的矿物、化学成分被风化流失，而耐风化、难流失的矿物、成分就残留，如花岗岩中的黑云母、长石可能先风化为碎屑、土，而耐风化的石英就残留。九华山风化壳是花岗岩风化后残留的碎屑与石英颗粒组成的碎屑堆积层，是植被生长与水分保持的基础物质。
Weathered Crust
Weathered crust is a discontinuous layer of autochthonous debris from weathered protolith. The its upper layer is earthy debris and the down one contains more and larger granular debris, and further down, debris materials are more rock fragments until to the whole rock, that is weathered crust profile. The weathered crust results from physical and chemical weathering of water, air, creatures and so on. Those
protolith’s minerals and chemical compositions weak against the weathering, like biotite and feldspar in granite, are easily weathered and lost; while those strong against weathering, like quartz, will be residuum to being main composition of debris. The Jiuhuashan weathered crust of granite mainly consists of quartz granules and debris, which are basic substance for plant growth and water conservation.
这里为什么有如儿童垒砌积木般的石头阵？它是花岗岩岩体被垂直方向和水平方向的节理交叉切割，再经风、水、冰、重力等的差异性风化剥离、分割出的较为规则的立方体石块的堆砌景观。
Natural Blocks Game: Granitic Blocks-piled up landscape
Why are there stacked rocks here as blocks game played by children? Being cross-incised by vertical and horizontal joints, and through differential weathering and stripping off by wind, water, ice and gravity and so on, granitic regular cubic rocks were produced and accumulated to form natural blocks game.
①发现有泥石流迹象，应设法从房屋里跑到开阔地带，观察地形，向沟谷两侧山坡或高地跑。不要顺沟方向逃生，切忌在泥石流中横渡。②逃生时，要抛弃一切影响奔跑速度的物品；③不要躲在有滚石和大量堆积物的陡峭山坡下面；④不要停留在低洼的地方，也不要攀爬到树上躲避。⑤不要停留在河道拐弯的凹岸或地方狭小的凸岸，这些地方容易受泥石流的冲刷淤埋，是危险地带。
九华山特有的森林景观，由原生的台湾松Pinus taiwanensis Hayata为主要树种的针叶林群落，林下有杜鹃Rhododendron simsii Planch灌丛，分布于九华山海拔900-1000米。台湾松是中国特有松属乔木树种，树形优美，生命力强，枝桠平展、粗韧。林内有野猪、白鹇、松鼠等野生动物出没。
Landscape of Pinus taiwanensis Hayata Community
As a unique forest landscape in Jiuhuashan, it is a coniferous forest community consisting of key species of protogenetic P. taiwanensis Hayata. Under its canopée is bush of Rhododendron simsii Planch. The such coniferous forest community distributes in altitude 900-1000m here. P. taiwanensis Hayata is unique Pinus arbor species in China with graceful tree form, strong vitality, spreading and tenacious branches.Wild animals like wild boars, Lophura nycthemera and squirrels appear here.
九华山是观赏和拍摄山地云海景观的最佳地点。云海作为特色气象景观是一定条件下形成的低于山顶高度的飘逸云层被人从高处俯首观赏，漫无边际的云层置于绿色山峰群岭之中，宛如临于大海之滨的人眺望蓝色海洋，故称“云海”。九华山云海主要发生在雨雪新霁之后，云海与奇松怪石交辉相映，蔚为壮观。
The Best Photography Spot for Cloud Sea
Jiuhuashan is the best place to enjoy and take photos of mountainous Cloud Sea landscape, a floating cloud layer forming under certain conditions as a special meteorological landscape below the mountain summit. When people on high spot overlooks, the boundless cloud layer is floating into green peaks and ridges, seeming that a person standing by coast view blue ocean, and it is why it is called Cloud Sea. Jiuhuashan Cloud Sea mainly happens in the sunny day right after sleet. Cloud Sea,bizarre pines and grotesque rocks enhance each other's beauty, rather spectacular and magnificent.
此处高2.2m，长9m，宽2~5m的花岗石状似玉如意，故称如意石。此为经风、水、冰沿花岗岩内的多组节理进行的反复风化剥蚀、剥落后形成。
Ruyi Rock
The granitic rock here, 2.2m high, 9m long and 2-5m wide, resembles Jade Ruyi, so it is called Ruyi Rock, which was formed through repeatedly weathering, denudation and peeling off by wind, water and ice along groups of joints in granite body.
台湾松Pinus taiwanensis Hayata，也称黄山松，是松科松属，乔木，中国特有树种。台湾松生长在海拔600米以上，针叶2针一束，稍硬直，长7-10厘米；喜光、深根性树种，喜凉润、耐瘠薄，但生长迟缓。台湾松生命力强，枝桠平展、粗韧，树形优美，具有很高的观赏价值。九华山的凤凰松（树龄1400年）、吉祥松、迎客松等景观树都是台湾松的精品代表。
Pinus taiwanensis Hayata
Pinus taiwanensis Hayata, also called Huangshan Pine, is Pinaceae,Pinus and arbor, unique species in China. P. taiwanensis Hayata grows above the altitude of 600m, and each bunch of leaves has two needles, slightly hard and straight, 7-10cm long. It is photophilous with deep root, and it likes cool and moist environment with poor soil tolerance, but it grows slowly. P. taiwanensis Hayata is species that has strong vitality, spreading tenacious branches, gracious tree form, and great aesthetic value. Phoenix Pine (1400 years old), Auspice Pine and Greeting Pine within Jiuhuashan are boutique representatives of P. taiwanensis Hayata.
花台因盛开杜鹃花得名。春季，鸟语花香，生机盎然；夏季，梦幻云海，气势磅礴；秋季，满山红叶，层林尽染；冬季，冰晶世界，纯洁肃穆。
Huatai Four Seasons’ Landscapes
Huatai name is because of blooming Rhododendra. In spring, birds here are twittering and flowers’ fragrance is everywhere with an exuberant appearance; in summer, cloud sea is fantastically fluctuating and magnificent; in autumn, the whole mountain is red leaves and trees are dressed in beautiful colors, in winter, comes world of ice and snow, pure and solemn.
正长花岗岩构成了九华山的主体。岩石的主要矿物有正长石、石英、黑云母等。正长石颜色为浅肉红色。此处岩石矿物颗粒的粒径0.3～5mm之间，属中细粒结构，故称中细粒正长花岗岩。
Medium-fine-grain Syenogranite
Syenogranite makes up of main body of Jiuhuashan Mt.and has main minerals of orthoclase, quartz and biotite. Orthoclase’s colour is light flesh pink. The grain size of the rock minerals here is 0.3-5mm, belonging to medium-fine-grained structure and so, it is called medium-fine-grain syenogranite.
九华山地区受新生代断块活动影响，沿九华山逆断裂带，上盘隆升为山地，形成南北绵延30余公里的九华山大型花岗岩石岭群峰；下盘下降成宽阔绵延起伏的丘陵、盆地。从九华山地质公园游客中心到花台顶峰的6km直线距离，完成了从盆地（平均海拔30m）到丘陵（平均海拔270m）再到山地山峰（平均海拔1000m以上）的地貌变化，即为“峰-丘-盆”的壮美景观。
Jiuhuashan area was impacted by Cenozoic fault-block movement. And hanging side of Jiuhuashan reverse fault zone was uplifted to become mountain land which is Jiuhuashan large-scaled granite peaks and ridges stretching 30km long in south-and-north direction. And heading side declined to become broad and gently rolling hill and basin. Within 6 km straight distance from Tourist Service Center of Jiuhuashan Geopark to Tianhua Peak., landform changes from basin (average altitude: 30m) to hill (average altitude: 270m) and to peak (average altitude: over 1000m), namely a spectacular peak-hill-basin landscape.
南北向九华大断裂的东、西两坡的地形地貌迥异，西坡地形陡峻，石柱、石墙、孤峰、深切沟谷等地貌发育，构造剥蚀景观突出；东坡坡度稍陡，坡形连续，侵蚀、剥蚀型地貌发育。这种断裂两侧、东西坡地形差异的动力一是坡度，二是构造，三是阳光降雨等自然要素，导致两坡地貌动力过程差异产生地貌差异。
Why are landforms on west and east slope of Jiuhuashan Mountains different?
The landforms on east and west slope of south-north Jiuhua Large Fault are different. The west slope is precipitous,and owns spectacular landscapes like stone pillar, stone wall, isolated peak and deep cleugh as well as prominent tectonic denudation landscape. The east slope is little steep, continuous and has eroded landform. Causes of two slopes’ different topography are mainly the followings, firstly gradient, secondly structure and thirdly natural factors like sunlight and rainwater. All of these made differential erosion and produced different landscapes.
